I thought there was a discussion about the equilibrium symbol here...Anyway, I thought it would be nice to point out that there are these symbols
⇌ (⇌
) and ⇋ (⇋
) in Unicode.

Apparently, anonymous 85.76.79.172 changed the picture of the {{ chem-stub}}. Shall we keep it or revert it? Wim van Dorst 21:35, 2005 Jun 21 (UTC).
Just to inform, there is a wikimedia latex for chemistry elements. Although it is not working in Wikipedia, it can be used to easily make chem graphics. See in WikiTeX
This is very interesting . See Wikipedia:Chemical image
I'd like to add information about polymers to Wikipedia, but I think there are two types of polymer information we can add. There's information just about particular polymers like nylon, polystyrene, etc...and there's information about polymer chemistry - how to actually make polymers. Would it be a good idea to make two subprojects, or just one to organize these topics? HappyCamper 04:00, 27 Apr 2005 (UTC)
I just learned of a new category: Category:Organic reactions. (Note the "s".) Unfortunately, this category already exists and is called: Category:Organic reaction. I feel we should consolidate these two nearly identical categories into one. The questions are: Which category should be merged into which? How do we do this? ~K 22:08, 22 May 2005 (UTC)
Category:Chemistry had a cleanup tag on it (about 500 articles), and so it got cleaned-up! The standard for category titles is the plural form, hence Category:Chemical reactions. Note that there is also a Category:Chemical processes which seemed useful in its own right for discussing industrial processes. The current category structure is by no means perfect, and any peer review would be welcome (especially of Category:Organic compounds and its sub-categories). And if anyone is really brave, the majority of articles in Category:Chemistry stubs are not correctly categorized: there are about a thousand to choose from... Person unknown 17:32, 5 Jun 2005 (UTC)
So sorry to bring you into this, but could a chemist answer the question of whether the suffix -ole in gasoline means
"A usually heterocyclic chemical compound containing a five-membered ring" or "A chemical compound, especially an ether, that does not contain hydroxyl"? - Omegatron 23:31, Jun 6, 2005 (UTC)
On a related note, I was looking into diesel fuel as it relates to biodiesel and found the diesel article surprisingly lacking in info on the fuel's chemical makeup. After I found one source (still looking for more) for the makeup of diesel and added a bit of that to the article, I reallized Wikipedia's coverage of the components of diesel fuel is rather wanting. I went looking for info on the physical and chemical properties of cycloparaffins and found very little, not to even mention some of the other components, or how they interact in the fuel as a whole. I posted the a question at cycloalkane but I don't know if that will be widely seen, so I thought I'd ask here. Additionally, some of the other components ot diesel fuel as listed in the source I found don't have Wikipedia articles at all. I don't know enough about this to even properly look up the information I want or to know it the names used in that source are standard or not. Anyway, hope this is the right place. Thanks - Taxman Talk 16:57, Jun 9, 2005 (UTC)
Originally, this was a stub with just a chemical equation. I put it up for Cleanup, but obviously nobody wanted to touch this subject. Then I did it myself, but my school days were in prehistoric times (more than 40 years ago) and my field of interest lies more in botany. Therefore, this article could use a review. I also wanted to write the chemical equation for the polyether formation (with red curved arrows showing the movement of the electrons) and the chemical formula for ethylene oxide, but this probably requires a special software. Anyway, take a fresh look at this article. There is probably much more to be said of these reactions. Furthermore the article : cationic addition polymerization still has to be written. JoJan 4 July 2005 19:50 (UTC)
To do the formulae and equations you will need a molecule editor: I prefer ACD/ChemSketch, others on WP:Chem use Isis ChemDraw (both available as freeware, links in article). Polymer articles are currently sitting on WikiProject Chemicals without much progress being made: any help, either through WP:Chem or through a new WikiProject would be more than welcome! Personally, I think that polymerization reactions and polymer properties should be treated by the same Project, more so than for other chemicals. Physchim62 5 July 2005 08:36 (UTC)
Related to chemistry, since they supposedly ionize air and shoot out magical ions and create ozone and blah blah marketing hype. Does anyone know how they really work? Check out the talk page for some other links.
"This article could use a careful review by an editor knowledgeable in chemistry."
So I asked here.- Omegatron 15:48, July 18, 2005 (UTC)
This probably non-notable czech chemist has a stub that's been sitting un-expanded since 2003. His CV is linked - it doesn't seem notable, but I wanted to alert you all in case he is, since I'm putting it up for VfD. Feel free to weigh in either for or against deletion. I hope he's notable, but the stub is tiny and wouldn't be much work to replace, if it is necessary. JesseW 07:39, 26 July 2005 (UTC)

I've requested that markup be added to simplify entering sub and superscript at Bug 3080. It's just TeX markup with mandatory brackets. I think it will clean up the markup and be a lot easier to type than HTML.
Examples:
x^{3}
→ x3 (powers)CO_{2}
→ CO2 (carbon dioxide symbol)1^{st}
→ 1st (ordinals)^{2}H_{2}O
→ 2H2O (isotopes)I can't think of anything this would conflict with, can you? Vote for it if you like it. Suggest a different syntax if you don't. Other syntaxes were suggested, which I really don't like. - Omegatron 21:27, August 9, 2005 (UTC)
I recently added a disambiguation page to cater for the various uses of the word abundance, and undertook some cleanup of the referents. I'm not sure what to do about this pair though:
Neither of the two leaf articles refers to the other. In fact, nothing correctly links to the latter (I fixed up the source error in Hydrogen, but left the two user-owned copies of the error.) Hv 11:35, 10 August 2005 (UTC)
I noticed that the page on Boric acid has it listed as having an NFPA rating of 4/4/4/ox, which I thought was unusual, since the article described it as a weak acid which has cosmetic and medical uses. I found some other sites that listed it as having different ratings, but they seem to disagree; one site lists it as 0/1/0, while another site lists it as 2/0/0. Since I don't actually know anything about chemistry, or have any appropriate reference books, I was hoping someone could find out. I hope this is an appropriate place to have posted this. Thanks. -- Creidieki 14:57, 10 August 2005 (UTC)
There are several active merge notices, I wondered if people might care to comment.
Category:Chemistry now has 172 articles in the main category. Many of these should be put in subcategories and taken out of the main cat. I don't know much about the subject. I'd appreciate any help.
Also, I created Template:Chem-cat to ask for help with this. But it has been listed at Wikipedia:Templates for deletion. Maurreen (talk) 23:08, 13 August 2005 (UTC)
It took a lot of work to reduce Category:Chemistry to just 172 articles, I'm really not optimistic that we can get it down much further. For comparison, Category:Chemistry stubs has nearly 700 articles. Lets try and keep the main category to a single page, then leave it at that. Physchim62 20:44, 24 September 2005 (UTC)
Hi, still working on Wikipedia:Missing science topics/Chemistry, and for that, someone redirected irreversible reaction to Reversible reaction. There was nothing there, so I pulled a bit from a couple sources. I'm no chemist, so I was hoping someone here could check that out fact wise and see they could improve it. As of yet I don't see the need for it to have it's own article as it is so small. Thanks - Taxman Talk 17:23, August 25, 2005 (UTC)
Hello, Please notice this project. I hope that the List of publications in chemistry will be adopted by the chemistry porject. Thanks, APH 06:33, 13 September 2005 (UTC)
Doctor Who has one, Bucharest has one, even James Bond has one, yes, I mean portals. Isn't it about time we created a chemistry Wikiportal? If so, who is going to set up Wikipedia:Wikiportal/Chemistry? Who is going to supervise it? I'm willing to lend a hand, but I don't have the technical know-how to run it. Walkerma 14:57, 24 September 2005 (UTC)
Thanks for setting that up, K, and I apologise if the link I gave above led to the wrong place (despite my copy & paste from another portal). I hope you don't mind that I declared it "open" and added the appropriate links to the lists, as it seemed pretty complete. I'd be happy to update it now & again, though I hope others will pitch in now & again too. See the portal at Portal:Chemistry. You did a nice job K, thanks a lot. Walkerma 16:35, 27 September 2005 (UTC)
I have a large collection of pictures of compounds, and I also know where there are some nice images, so I can probably manage to change the picture every month or so, if that's OK. Walkerma 20:58, 27 September 2005 (UTC)
Great work K! I will try to keep an eye on the 'Things to do' section as I rabbit around the various chemistry categories. Physchim62 14:12, 28 September 2005 (UTC)
I have put up a picture of Wöhler on the Wikiportal to make a change (and to see if I could do it!), but I had a question for those more knowledgable. The original picture is 303k, but I shrunk it down somewhat (it's a jpg, rather big, but it's a nice portrait). If someone is looking at this via modem, do they have to download all 303k, or does the Wiki software automatically reduce that if the picture is smaller? If they have to download it all, we should probably limit the picture to around 60k IMHO. Walkerma 16:35, 11 October 2005 (UTC)
Hi, I'm not a project member but I'd like to contribute a little. I've found some icons that you may wish to consider using in your project.

There are 8 chemistry-related Featured Articles, which is fine for the next 7 months. My question to WPChem is should we consider other articles for the 'Featured Article' section of our Portal? ~K 16:15, 23 October 2005 (UTC)
