Amalgam (chemistry) defines itself as a "substance formed by the reaction of mercury with another metal" (links omitted, italics mine). It never says it is an alloy, but that term is used in one of the later sections and the alloy article gives amalgams as an example. There are scattered questions over years on the talkpage asking several related questions, getting at the concern that the article never really discusses the nature of this "reaction" or its resulting "substance". How is it other than just an alloy where one of the components is specifically mercury? DMacks ( talk) 16:01, 24 January 2014 (UTC)

This is rated as high importance but is a stub because the salt (NH4)3PO4 is unstable. I suspect the importance stems from the use of ammonium phosphates in agriculure, but the fertilizer ammonium phosphates are diammonium phosphate and monoammonium phosphate which are both rated as low importance, the former is a "stub" and the latter a "start". There is also an ammonium phosphate (compounds) index page. Could we possibly change the importance rating on these compounds? Axiosaurus ( talk) 14:05, 27 January 2014 (UTC)

I noticed that the stereochemistry of chlorinated
norbornene is opposed. In the case of
chlordane,
dieldrin,
endosulfan and

whereas for
aldrin and
endrin the substituent is “downwards” endo.

If the commercially available, widely-used form of the pesticide genuinely contains a mixture of isomers, we should probably discuss this in detail in a section on structure and composition, and the skeletal formula and 3D models should be presented there rather than in the chembox. For others, where the images truly represent what's in the bottle, the chembox is the best place for them. I agree the skeletal formulae should be redrawn.

As Wikipedian in Residence at the Royal Society, the National Academy for the sciences of the UK, I am pleased to say that the two Royal Society History of Science journals will be fully accessible for free for 2 days on March 4th and 5th. This is in conjunction with the Women in Science Edit-a-thon on 4 March, slightly in advance of International Women's Day, on Saturday March 8th. The event is held by the Royal Society and the Royal Academy of Engineering, and is fully booked, but online participation is very welcome, and suggestions for articles relevant to the theme of "Women in Science" that need work, and topics that need coverage.
The journals will have full and free online access to all from 1am (GMT/UTC) on 4th March 2014 until 11pm (GMT/UTC) on 5th March 2014. Normally they are only free online for issues between 1 and 10 years old. They are:

Would you be interested in participating in a user study? We are a team at University of Washington studying methods for finding collaborators within a Wikipedia community. We are looking for volunteers to evaluate a new visualization tool. All you need to do is to prepare for your laptop/desktop, web camera, and speaker for video communication with Google Hangout. We will provide you with a Amazon gift card in appreciation of your time and participation. For more information about this study, please visit our wiki page ( http://meta.wikimedia.org/wiki/Research:Finding_a_Collaborator). If you would like to participate in our user study, please send me a message at Wkmaster ( talk) 07:53, 16 April 2014 (UTC).
Is there a reason that this project uses statistics-only subpages in the form subject name (data page)? I noticed this when encountering Trichlorofluoromethane (data page) during new page patrol, and I then saw that there are some 150 similar pages.
Most of these seem to be perfect for inclusion in their main page, neither the main article nor the subpage are too long (e.g. in this case Trichlorofluoromethane wouldn't have a problem with the expansion that this "data page" would produce, the same applies to e.g. Dichlorodifluoromethane (data page) or a revised form of Fucitol (data page)). This would improve the main pages, decrease the number of unnecessary pages (it isn't really user-friendly to spread the info across multiple pages), and better match what other projects do and what the general policies indicate (e.g. WP:NOT opposes pages which consist only of statistics and the like). A page like Fucitol (data page) is really not what a Wikipedia article should look like, and I see no problem that is solved by making these separate page. By the way, Pyrene (data page) has been vandalized (or made more correct, whatever) since March 2009, i.e. 5 years ago: [1]. Fram ( talk) 10:03, 1 April 2014 (UTC)
I've never worked much with the data pages, though I was aware of their existence. In my view, the chembox in the top-right corner is important, and should carry the pertinent data for the compounds, the important (I know that it is a subjective term) properties - I think we can agree about boiling and melting points, density, refractive index, vapour pressures, commonly used alternative names, links to appropriate similar compounds. Some are 'edgy' - I can see the crystal lattice constants for important crystalline compounds (CaSO4, also found as a mineral, water ('common ice'-variety), but for others that is information that is less generally 'useful' (crystals of ethanol? Anyone outside of specific corner of chemistry would even encounter crystals and have use for the lattice constants?) and then that data should be 'separate'.
-- DrKC MD ( talk) 20:37, 18 April 2014 (UTC) I think it is the best that a 'second' chembox-like template would be constructed, which goes into the bottom part, is page-wide, and is standard collapsed. It should have most of the parameters from the chembox (except maybe for the parameters which will ALWAYS be mentioned in the chembox if known, like boiling point and the common chemical identifiers), and probably also parameters which will never appear in the chembox (IR-absorption-frequencies, NMR-signal positions, multiplicity, and intensity, maybe even images of spectra?). It could have a modular approach like the chembox, but with multiple columns
My suggestion: everything can go into the bottom box, the data in the chembox should either be that which are either common and are related to readily observable properties (melting point & boiling point -> is it a solid, liquid, gas; density - heavier or lighter than water; colour - how does it look like), or are of interest significantly outside of the field of chemistry for that chemical (the example of crystal structure, if the compound is relating to minerals, it links to mineralogists and to the-man-in-the-street with an interest in minerals (hobby)). It might make some of the massive chemboxes a bit smaller if some data was moved, and some data could be compacted (some chemboxes have data for 4 stereoisomers and the racemate, whereas the-man-in-the-street generally only encounters one specific stereoisomer (in the case of medicine or natural products), or only the racemate - move the data for other 4 to the bottom box). -- Dirk Beetstra T C 08:29, 2 April 2014 (UTC)

After a recent request, I added WikiProject Chemicals to the list of projects to compile monthly pageview stats for. The data is the same used by http://stats.grok.se/en/ but the program is different, and includes the aggregate views from all redirects to each page. The stats are at Wikipedia:WikiProject Chemicals/Popular pages.
The page will be updated monthly with new data. The edits aren't marked as bot edits, so they will show up in watchlists. You can view more results, request a new project be added to the list, or request a configuration change for this project using the Tool Labs tool. If you have any comments or suggestions, please let me know. Thanks! Mr. Z-man 02:31, 4 June 2014 (UTC)
Hi all,
My name is Adi Khajuria and I am helping out with Wikimania 2014 in London.
One of our initiatives is to create leaflets to increase the discoverability of various wikimedia projects, and showcase the breadth of activity within wikimedia. Any kind of project can have a physical paper leaflet designed - for free - as a tool to help recruit new contributors. These leaflets will be printed at Wikimania 2014, and the designs can be re-used in the future at other events and locations.
This is particularly aimed at highlighting less discoverable but successful projects, e.g:
• Active Wikiprojects: Wikiproject Medicine, WikiProject Video Games, Wikiproject Film
• Tech projects/Tools, which may be looking for either users or developers.
• Less known major projects: Wikinews, Wikidata, Wikivoyage, etc.
• Wiki Loves Parliaments, Wiki Loves Monuments, Wiki Loves ____
• Wikimedia thematic organisations, Wikiwomen’s Collaborative, The Signpost
For more information or to sign up for one for your project, go to:

An editor claiming to be Gad M. Gilad, Ph.D. has recently made substantial changes to Agmatine. Please see my comments on Talk:Agmatine. The editor is a scientist who sells agmatine supplements (neurofencine). I do not assume the edits were made in bad faith; however, after a very brief look, I have found at least one statement that strikes me as questionable (again, see the article's talk page). I would appreciate anyone's efforts to review the recent changes, and remove any that may not have been in good faith. — νημινυλι ( talk) 05:33, 21 June 2014 (UTC)

Could someone with more knowledge (and journal access) than I check out this series of edits to aluminium hydride? They look legitimate, but something in the wording sets off my suspicions. Pi.1415926535 ( talk) 13:20, 6 August 2014 (UTC)
A series of new articles on hemiaminals were recently created. I'm concerned that these are non-notable compounds. In fact, I'm not sure that they even exist except theoretically or perhaps transiently (they will readily decompose into an aldehyde and ammonia). All the articles are also unreferenced.
Should they be kept or nominated for deletion? ChemNerd ( talk) 12:52, 15 August 2014 (UTC)
Here are some more...
I have invited Zuloo37, the creator of all these articles, to contribute to the discussion here. -- Ed ( Edgar181) 00:35, 18 August 2014 (UTC)
The way I saw it, no one had written about these yet, and they seemed important. While it is true that in water, they can decompose into ammonia and an aldehyde, we only experience such an event on this oxygenated planet. I feel like life on other planets (ex. Titan, with liquid methane) could possibly use poly amino alcohols as proteins rather than the oxidized amino acids. 1-Aminoethanol and 2-Aminoethanol are isomers, but they are both real compounds with different properties that I think deserve independent pages. Using the same language as for amino acids, but simply adding "aminol" seems to describe them pretty well, I think. Moving them to a Geminal amino alcohol page or adding a new section on the Amino alcohol page is a good idea. I made models for all the compounds and started making the articles, hoping that people would consider them and find their properties. One of the pages I made already had properties added to it, 1-Amino-1-propanol. Even if they are unstable in a strong solvent like water, the pages should still exist and say why they're unstable, because I see no reason for them to be, if using ammonia or methane as a solvent. -- User:zuloo37 ( User talk:zuloo37) 03:55, 18 August 2014 (UTC)
Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej ( talk) 22:47, 1 October 2014 (UTC)

I am copying comments I made on the ethyl sulfate (ethyl hydrogen sulfate) page to here. I am not sure how to go about getting this corrected.== Boiling and melting point. The boiling and melting point given are the same as for diethyl sulphate. This strikes me as very unlikely. I have verified that diethyl sulphate has the boiling and melting points listed, but I cannot find the values for ethyl hydrogen sulphate. I am almost sure that these have been mixed up, and it should say that the values are unknown if the correct values cannot be determined. Stainless316 ( talk) 13:41, 13 November 2014 (UTC)
This reference http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?sid=162221653#x27
gives BPt 209.5 with decomposition and MPt -25°C - exactly the same as diethyl sulfate. However, this reference also gives specific gravity/density as 1.172 - similar to diethy sulfate's wiki entry of 1.2, rather than wiki entry for ethyl hydrogen sulfate of 1.46. The reference often specifically refers to diethyl sulfate in other sections. I believe that this reference has mixed up ethyl hydrogen sulfate and diethyl sulfate. It also seems likely that this mix up has occurred elsewhere, and has been mis-applied in the wiki entry. I cannot find the boiling point and melting point of ethyl hydrogen sulfate. Stainless316 ( talk) 13:12, 14 November 2014 (UTC)
I noticed this because I needed to know the boiling point for ethyl sulfate, and the incorrect information was a problem for me. Stainless316 ( talk) 09:53, 25 November 2014 (UTC)
Take Sodium metasilicate as a simple example. The anhydrous form contains a polymeric anion. The hydrated forms contain discrete silicate ions with 4 coordinate silicon. Chemspider names the compound as disodium oxosilanediolate with an image that shows SiO32– anions, implying that there are indeed three coordinate silicate anions present.
I queried their structure for sodium aluminium silicate, (which they take to be NaAlSi2O6, the mineral jadeite) which shows discrete SiO32– with a systematic name of "Aluminium sodium oxosilanediolate (1:1:2)" . I got this response.
"To explain ChemSpider is a database of chemical structures, but only stores primary structure data -things at the molecular level (atoms, bonds etc) it does't hold data on supramolecular or extended structures (eg how molecules are arranged in ordered materials) - nor can it distinguish between two materials that have the same molecular structure but different supramolecular structure - for instance Calcite, aragonite and vaterite are all percieved as the same. But we can provide links out to resources that do have pages/entries that do distinguish these materials."
Molecules in calcium carbonate- whatever next. Chemspider has an "RSC" endorsement so should be considered to be authoritative. If it were any other site that showed such a structure we wouldn't link, would we? Axiosaurus ( talk) 11:29, 29 November 2014 (UTC)

We are looking for volunteers to evaluate a new visualization tool. All you need to do is to prepare for your laptop/desktop, web camera, and speaker for video communication with Google Hangout. We will provide you with a Amazon gift card in appreciation of your time and participation. For more information about this study, please visit our wiki page ( http://meta.wikimedia.org/wiki/Research:Finding_a_Collaborator). If you would like to participate in our user study, please send me a message at Wkmaster ( talk) 07:53, 16 April 2014 (UTC).
Is there a reason that this project uses statistics-only subpages in the form subject name (data page)? I noticed this when encountering Trichlorofluoromethane (data page) during new page patrol, and I then saw that there are some 150 similar pages.
Most of these seem to be perfect for inclusion in their main page, neither the main article nor the subpage are too long (e.g. in this case Trichlorofluoromethane wouldn't have a problem with the expansion that this "data page" would produce, the same applies to e.g. Dichlorodifluoromethane (data page) or a revised form of Fucitol (data page)). This would improve the main pages, decrease the number of unnecessary pages (it isn't really user-friendly to spread the info across multiple pages), and better match what other projects do and what the general policies indicate (e.g. WP:NOT opposes pages which consist only of statistics and the like). A page like Fucitol (data page) is really not what a Wikipedia article should look like, and I see no problem that is solved by making these separate page. By the way, Pyrene (data page) has been vandalized (or made more correct, whatever) since March 2009, i.e. 5 years ago: [1]. Fram ( talk) 10:03, 1 April 2014 (UTC)
I've never worked much with the data pages, though I was aware of their existence. In my view, the chembox in the top-right corner is important, and should carry the pertinent data for the compounds, the important (I know that it is a subjective term) properties - I think we can agree about boiling and melting points, density, refractive index, vapour pressures, commonly used alternative names, links to appropriate similar compounds. Some are 'edgy' - I can see the crystal lattice constants for important crystalline compounds (CaSO4, also found as a mineral, water ('common ice'-variety), but for others that is information that is less generally 'useful' (crystals of ethanol? Anyone outside of specific corner of chemistry would even encounter crystals and have use for the lattice constants?) and then that data should be 'separate'.
-- DrKC MD ( talk) 20:37, 18 April 2014 (UTC) I think it is the best that a 'second' chembox-like template would be constructed, which goes into the bottom part, is page-wide, and is standard collapsed. It should have most of the parameters from the chembox (except maybe for the parameters which will ALWAYS be mentioned in the chembox if known, like boiling point and the common chemical identifiers), and probably also parameters which will never appear in the chembox (IR-absorption-frequencies, NMR-signal positions, multiplicity, and intensity, maybe even images of spectra?). It could have a modular approach like the chembox, but with multiple columns
My suggestion: everything can go into the bottom box, the data in the chembox should either be that which are either common and are related to readily observable properties (melting point & boiling point -> is it a solid, liquid, gas; density - heavier or lighter than water; colour - how does it look like), or are of interest significantly outside of the field of chemistry for that chemical (the example of crystal structure, if the compound is relating to minerals, it links to mineralogists and to the-man-in-the-street with an interest in minerals (hobby)). It might make some of the massive chemboxes a bit smaller if some data was moved, and some data could be compacted (some chemboxes have data for 4 stereoisomers and the racemate, whereas the-man-in-the-street generally only encounters one specific stereoisomer (in the case of medicine or natural products), or only the racemate - move the data for other 4 to the bottom box). -- Dirk Beetstra T C 08:29, 2 April 2014 (UTC)
A discussion is taking place on the title of this article at Talk:Halite#Requested_move. All input welcome. Thank you. walk victor falk talk 15:07, 4 May 2014 (UTC)
After a recent request, I added WikiProject Chemicals to the list of projects to compile monthly pageview stats for. The data is the same used by http://stats.grok.se/en/ but the program is different, and includes the aggregate views from all redirects to each page. The stats are at Wikipedia:WikiProject Chemicals/Popular pages.
The page will be updated monthly with new data. The edits aren't marked as bot edits, so they will show up in watchlists. You can view more results, request a new project be added to the list, or request a configuration change for this project using the Tool Labs tool. If you have any comments or suggestions, please let me know. Thanks! Mr. Z-man 02:31, 4 June 2014 (UTC)
Hi all,
My name is Adi Khajuria and I am helping out with Wikimania 2014 in London.
One of our initiatives is to create leaflets to increase the discoverability of various wikimedia projects, and showcase the breadth of activity within wikimedia. Any kind of project can have a physical paper leaflet designed - for free - as a tool to help recruit new contributors. These leaflets will be printed at Wikimania 2014, and the designs can be re-used in the future at other events and locations.
This is particularly aimed at highlighting less discoverable but successful projects, e.g:
• Active Wikiprojects: Wikiproject Medicine, WikiProject Video Games, Wikiproject Film
• Tech projects/Tools, which may be looking for either users or developers.
• Less known major projects: Wikinews, Wikidata, Wikivoyage, etc.
• Wiki Loves Parliaments, Wiki Loves Monuments, Wiki Loves ____
• Wikimedia thematic organisations, Wikiwomen’s Collaborative, The Signpost
For more information or to sign up for one for your project, go to:

An editor claiming to be Gad M. Gilad, Ph.D. has recently made substantial changes to Agmatine. Please see my comments on Talk:Agmatine. The editor is a scientist who sells agmatine supplements (neurofencine). I do not assume the edits were made in bad faith; however, after a very brief look, I have found at least one statement that strikes me as questionable (again, see the article's talk page). I would appreciate anyone's efforts to review the recent changes, and remove any that may not have been in good faith. — νημινυλι ( talk) 05:33, 21 June 2014 (UTC)
The Pesticide Properties Database (PPDB) is linked from > 100 articles. What about creating a template (like in de.wikipedia)? -- Leyo 22:45, 24 April 2014 (UTC)
I created Template:PPDB. It would be good to have it inserted to these articles in an automated manner. -- Leyo 22:41, 23 June 2014 (UTC)

We have some 125 element infoboxes (see Category:Periodic table infobox templates). I have prepared changes to change the box into a wiki-standard {{ Infobox}}. See Change_Infobox_element_to_use_{Infobox} for an overview and comments. Some questions are open.
You can check your favorite element for changes (e.g., fluorine). An all-parameter demo is here. - DePiep ( talk) 13:25, 18 July 2014 (UTC)

Could someone with more knowledge (and journal access) than I check out this series of edits to aluminium hydride? They look legitimate, but something in the wording sets off my suspicions. Pi.1415926535 ( talk) 13:20, 6 August 2014 (UTC)
A series of new articles on hemiaminals were recently created. I'm concerned that these are non-notable compounds. In fact, I'm not sure that they even exist except theoretically or perhaps transiently (they will readily decompose into an aldehyde and ammonia). All the articles are also unreferenced.
Should they be kept or nominated for deletion? ChemNerd ( talk) 12:52, 15 August 2014 (UTC)
Here are some more...
I have invited Zuloo37, the creator of all these articles, to contribute to the discussion here. -- Ed ( Edgar181) 00:35, 18 August 2014 (UTC)
The way I saw it, no one had written about these yet, and they seemed important. While it is true that in water, they can decompose into ammonia and an aldehyde, we only experience such an event on this oxygenated planet. I feel like life on other planets (ex. Titan, with liquid methane) could possibly use poly amino alcohols as proteins rather than the oxidized amino acids. 1-Aminoethanol and 2-Aminoethanol are isomers, but they are both real compounds with different properties that I think deserve independent pages. Using the same language as for amino acids, but simply adding "aminol" seems to describe them pretty well, I think. Moving them to a Geminal amino alcohol page or adding a new section on the Amino alcohol page is a good idea. I made models for all the compounds and started making the articles, hoping that people would consider them and find their properties. One of the pages I made already had properties added to it, 1-Amino-1-propanol. Even if they are unstable in a strong solvent like water, the pages should still exist and say why they're unstable, because I see no reason for them to be, if using ammonia or methane as a solvent. -- User:zuloo37 ( User talk:zuloo37) 03:55, 18 August 2014 (UTC)
Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej ( talk) 22:47, 1 October 2014 (UTC)
The ESIS website closed its service. There are lots of articles that now have a dead link: Special:LinkSearch/esis.jrc.ec.europa.eu. I guess that we need to find alternative links as replacements. -- Leyo 04:53, 19 November 2014 (UTC)

I am copying comments I made on the ethyl sulfate (ethyl hydrogen sulfate) page to here. I am not sure how to go about getting this corrected.== Boiling and melting point. The boiling and melting point given are the same as for diethyl sulphate. This strikes me as very unlikely. I have verified that diethyl sulphate has the boiling and melting points listed, but I cannot find the values for ethyl hydrogen sulphate. I am almost sure that these have been mixed up, and it should say that the values are unknown if the correct values cannot be determined. Stainless316 ( talk) 13:41, 13 November 2014 (UTC)
This reference http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?sid=162221653#x27
gives BPt 209.5 with decomposition and MPt -25°C - exactly the same as diethyl sulfate. However, this reference also gives specific gravity/density as 1.172 - similar to diethy sulfate's wiki entry of 1.2, rather than wiki entry for ethyl hydrogen sulfate of 1.46. The reference often specifically refers to diethyl sulfate in other sections. I believe that this reference has mixed up ethyl hydrogen sulfate and diethyl sulfate. It also seems likely that this mix up has occurred elsewhere, and has been mis-applied in the wiki entry. I cannot find the boiling point and melting point of ethyl hydrogen sulfate. Stainless316 ( talk) 13:12, 14 November 2014 (UTC)
I noticed this because I needed to know the boiling point for ethyl sulfate, and the incorrect information was a problem for me. Stainless316 ( talk) 09:53, 25 November 2014 (UTC)
Take Sodium metasilicate as a simple example. The anhydrous form contains a polymeric anion. The hydrated forms contain discrete silicate ions with 4 coordinate silicon. Chemspider names the compound as disodium oxosilanediolate with an image that shows SiO32– anions, implying that there are indeed three coordinate silicate anions present.
I queried their structure for sodium aluminium silicate, (which they take to be NaAlSi2O6, the mineral jadeite) which shows discrete SiO32– with a systematic name of "Aluminium sodium oxosilanediolate (1:1:2)" . I got this response.
"To explain ChemSpider is a database of chemical structures, but only stores primary structure data -things at the molecular level (atoms, bonds etc) it does't hold data on supramolecular or extended structures (eg how molecules are arranged in ordered materials) - nor can it distinguish between two materials that have the same molecular structure but different supramolecular structure - for instance Calcite, aragonite and vaterite are all percieved as the same. But we can provide links out to resources that do have pages/entries that do distinguish these materials."
Molecules in calcium carbonate- whatever next. Chemspider has an "RSC" endorsement so should be considered to be authoritative. If it were any other site that showed such a structure we wouldn't link, would we? Axiosaurus ( talk) 11:29, 29 November 2014 (UTC)

I have made extensive corrections to this article. (CuCO3 is not known or at best is very unstable - the article described the basic carbonate, Cu2(OH)2CO3), malachite). Can someone with admin please move the article to "basic copper carbonate" and change copper(II) carbonate to a redirect. I have removed a lot of chembox info. relating to the so called CuCO3 that points to chemspider etc so could someone please check I have got rid of all the relevant flags etc. I have assigned the CAS # using the Rubber bible.
