Merge Mercury(I) ion
[edit]
ResolvedMercury(I) ion is a stub article that has even less content than the relevant section in this article. I don't see why it needs to exist. We should just fold it into this article.—Tetracube (talk) 23:42, 28 April 2010 (UTC)
- Support. I already did merge it. Unfortunately, someone undid that merge without explanation. Obviously, there's no need, given the relatively small amount of content in both articles, why we need two articles on the same subject when one will do. Unless I can get a satisfactory reason why it was undone, I exprect to return the merge in a few days. --Jayron32 01:20, 29 April 2010 (UTC)
- I agree with User:Jayron32 , mercury(I) should redirect to Mercury polycations V8rik (talk) 21:51, 29 April 2010 (UTC)
Equilibrium
[edit]The text says that "Hg2+2 is stable in aqueous solution, where it is in equilibrium with Hg2+ and elemental Hg, with Hg2+ present at around 0.6%". The latter value seems meaningless without specifying the concentration of the species. The equilibrium constant(s) should be more meaningful. --Jorge Stolfi (talk) 15:30, 11 July 2018 (UTC)
The text also says "This equilibrium is readily shifted by the addition of an anion which forms an insoluble Hg(II) salt, such as S2−
, which causes the Hg(I) salt to completely disproportionate, or by the addition of an anion which forms an insoluble Hg(I) salt, such as Cl−
, which causes the elemental mercury and Hg2+ to completely recombine into the mercury(I) salt." However, mercury(I) sulfide is insoluble too, so Hg
2S should precipitate preferentially to HgS and Hg
2. Indeed there are old papers that claim that Hg
2S can be obtained that way, by starting with very dilute solutions of a Hg2+
2 salt and working at -10°C. --Jorge Stolfi (talk) 15:30, 11 July 2018 (UTC)
