This section gives a good account of the historical facts, but the conclusion is now known to be wrong - see Greenwood, Norman N.; Earnshaw, Alan (1997). Chemistry of the Elements (2nd ed.). Butterworth-Heinemann. ISBN 978-0-08-037941-8. p. 1099. Hb-O2 is a complex of low-spin iron(II) with the oxygen molecule. The angle Fe-O-O is not 180°. The non-linearity destroys the degeneracy of the π* orbitals and so the electrons which have paralell spins in the oxygen molecule can pair up in the complex at a lower energy cost than is required to form the singlet state in the isolated oxygen molecule. This section therefore need more attention than I feel qualified to give, as I'm not expert in biochemistry. Petergans ( talk) 14:12, 17 March 2010 (UTC)

As I understand the term amino acid is restricted to compounds with the structure NH2CH(R)CO2H. EDTA does not have an NH2 constituent.
"Sodium silicate" is too specific, it suggests a particular compound like Na2SiO3, which anyway would be dissociated in solution. The sodium ion plays no part in the reaction.

"Ammonium diuranate", the major component of yellow cake, is misnamed and does not have the formula [NH42U2O7. It approximates to the gross formula 3 UO3· NH3·5 H2O (Cordfunke, E.H.P. (1962). "On the uranates of ammonium—I: The ternary system NH3---UO3---H2O". J. Inorg. Nucl. Chem. 24 (3): 303–307. doi: 10.1016/0022-1902(62)80184-5.)
I have serious doubts about the formulae of the other so-called diuranates, sodium diuranate (Na2U2O7) and magnesium diuranate (MgU2O7. The reason is that there are no 4-coordinate complexes of uranium(VI) known, so the analogy with dichromate is false. Can anyone help? Petergans ( talk) 11:03, 24 January 2011 (UTC)
I have downloaded several papers on diuranates and the overall image is a little confusing.--12:44, 28 January 2011 (UTC)
I was away when you wrote me and then entirely forgot about it, apologies. We don't have diuranates in our database. I've looked Web of Science (I suppose you have access to it, let me know if not). It gives 77 entries and a number of structural studies like [1] [2] (can't download due to limitations of my current affiliation). From what I can read, I concur that it is usually a mixture (by production nature), but it can be purified by processing, e.g. annealing which removes water. This describes a tentative evolution with heating from various hydrates to Na2U2O7. My feeling after some reading is that there is no much doubt about existence of complexes like A2U2O7 and (AE)U2O7 (A=alkali, AE=Alkali earth). Materialscientist ( talk) 02:00, 4 February 2011 (UTC)

Petergans, I updated the lead of the article to include mention of semantic. The hook was taken directly from the source, and directly corresponds the article. The Pinocchio paradox is the Liar paradox, if for nothing else than at least because it is said so clearly and unconditionally in the main source: "is clearly a version of the Liar.". I hope you do agree now that the Pinocchio paradox has nothing to do with Pinocchio being "a known liar", and that it is the Liar paradox. There's no any valid reason for your objection. May I please ask you either to say clearly what in your opinion is wrong with the hook or remove you objections? I'd be happy to respond all your questions either here or at the article talk page. Thanks.-- Mbz1 ( talk) 15:07, 13 February 2011 (UTC)
I am sorry to come to your talk page once again, but you said you will not comment on the hook anymore. It is my understanding that your objections now is only about the hook linking to Liar paradox.

I do hope that now, you could go ahead and remove your objections.-- Mbz1 ( talk) 17:24, 13 February 2011 (UTC)

You might have some thoughts on a possible article on metal aquo complexes. We have several articles on various types of metal complexes, such as metal carbonyl complexes, metal nitrosyl complexes, even metal sulfur dioxide complexes. But the most fundamental would be on simple aquo compounds, such as [M(H2O)6n+. Some properties of interest would be water exchange rates, absorption spectra, pKa's and even E1/2's.

Hi Peter, I saw that you commented out my image at Triglycine sulfate. Depicting chemical structures that contain both acidic and basic groups always presents a bit of difficulty. In most cases, it is standard practice to show such compounds in their neutral form because the protonation states of various groups can depend on conditions (solid state, in solution, etc). I don't mind if you would like to replace the image with something else, but in the absence of an alternate, I think File:Triglycine sulfate.svg is perfectly reasonable. It is similar to what is shown at PubChem, ChemSpider, and other chemical databases. Let me know what you think. -- Ed ( Edgar181) 13:28, 6 May 2011 (UTC)

I was intending to write the article with this topic but by browsing Wikipedia I have noticed your development of the subject in your test page and I hope you don′t mind I′ve taken the liberty to initialize the article that was missing with content from your test page. I have made very small modifications concerning categories.-- MagnInd ( talk) 21:46, 15 February 2011 (UTC)
On 18 February 2011, Did you know? was updated with a fact from the article Uranate, which you created or substantially expanded. The fact was ... that uranates have been used to add various colors to glass (example pictured)? You are welcome to check how many hits the article got while on the front page ( here's how, quick check) and add it to DYKSTATS if it got over 5,000. If you know of another interesting fact from a recently created article, then please suggest it on the Did you know? talk page. |

Excellent work. Can I recommend you nominate this for a good article? Uranate should also be good enough.♦ Dr. Blofeld 17:36, 23 February 2011 (UTC)
I like the article, good work.-- Stone ( talk) 17:42, 23 February 2011 (UTC)
You might have some thoughts on a possible article on metal aquo complexes. We have several articles on various types of metal complexes, such as metal carbonyl complexes, metal nitrosyl complexes, even metal sulfur dioxide complexes. But the most fundamental would be on simple aquo compounds, such as [M(H2O)6n+. Some properties of interest would be water exchange rates, absorption spectra, pKa's and even E1/2's. Leave a note here if you have some recommendations and especially about possible sources. Your role here has been very positive. -- Smokefoot ( talk) 05:36, 5 March 2011 (UTC)

Hi Petergans. Please comment there. You removed the image from the article two month ago. -- Leyo 20:13, 30 March 2011 (UTC)
On 31 March 2011, Did you know? was updated with a fact from the article Metal ions in aqueous solution, which you created or substantially expanded. The fact was ... that the second hydration shell of chromium(III) in aqueous solution contains around 13 water molecules?

Hi Peter, I saw that you commented out my image at Triglycine sulfate. Depicting chemical structures that contain both acidic and basic groups always presents a bit of difficulty. In most cases, it is standard practice to show such compounds in their neutral form because the protonation states of various groups can depend on conditions (solid state, in solution, etc). I don't mind if you would like to replace the image with something else, but in the absence of an alternate, I think File:Triglycine sulfate.svg is perfectly reasonable. It is similar to what is shown at PubChem, ChemSpider, and other chemical databases. Let me know what you think. -- Ed ( Edgar181) 13:28, 6 May 2011 (UTC)

Greetings: Requesting your rationale for eliminating the solubility product table from Solubility Product. I hadn't had need to look up anything on it for a while, and today, when I did have need of it, I found it to have been cut in July 2010. As you undoubtedly know, the solubility product table does _not_ duplicate the data in the Solubility Table. Karl Hahn ( T) ( C) 19:29, 11 December 2011 (UTC)
I've added two odd images to your sandbox without explanation, hoping you can use them: in Ti[ClO4]4, O and Cl atoms sort of exchange places compared to usual oxohalides, and [AgOTeF5−(C6H5CH3)2]2 is an example of a split site in a M-O-M chain. I saw a similar structure for Tl, but with a slightly different organic part. Materialscientist ( talk) 07:47, 27 December 2011 (UTC)
I have reviewed your article Oxohalide for DYK and have suggested an alternative hook which you may like to consider. Cwmhiraeth ( talk) 07:45, 3 January 2012 (UTC)
On 26 January 2012, Did you know? was updated with a fact from the article Oxohalide, which you created or substantially expanded. The fact was ... that some oxohalide ions contain a linear M—O—M structure (where M = W, Ru, Os)?

Hi - Can you have a look at Talk:Equilibrium constant#Ionic Strength Comment? We are trying to understand a statement you inserted 5 years ago to the effect that K is best determined at high ionic strength. Yes, that keeps the activity coefficients constant, but can you explain briefly how to correct for them? (It is probably best to answer there, not here). Dirac66 ( talk) 17:50, 26 April 2012 (UTC)

Just so I'm clear, are you saying that every time just 'octanol' is mentioned, that it should not got to 1-Octanol, but to the disambiguation page as the reference could be to any of the other octanols? I want to be sure before I undo the changes. Also, until 3 days ago, every 'octanol' link went to 1-Octanol. - Niceguyedc Go Huskies! 17:24, 23 October 2012 (UTC)
Peter: your picture is really good and valuable. I wondered if it would be possible to add any additional info on the source of the data or the model used to create it? Just a thought, to extend the excellent usefulness of this figure even further... Cheers, Stan J. Klimas ( talk) 07:52, 13 December 2012 (UTC).
