Talk:Potassium manganate

Article structure
This article resulted from my subdividing Manganate so that we had a real data table on a real compound vs just an anion. So the writing might be a little redundant between the two reports - feel free to revise and parse as you see fit. --Smokefoot 02:41, 20 May 2006 (UTC)

Dubious comment
I removed the bold sentence below (my boldening):
 * In the laboratory, K2MnO4 can be synthesized by heating a solution of KMnO4 in concentrated KOH solution followed by cooling to give green crystals:
 * 4 KMnO4 + 4 KOH  →  4 K2MnO4 +  O2 +  2 H2O
 * This reaction illustrates the relatively rare role of hydroxide as a reducing agent. Solutions of K2MnO4 are generated by allowing a solution of KMnO4 in 5–10 M KOH to stir for a day at room temperature followed by removal of MnO2, which is insoluble.

The bold comment does not make sense given the equation above. Perhaps it was meant for the "opposite" reaction, the disproportionation of K2MnO4 into KMnO4 + MnO2? --Jorge Stolfi (talk) 19:50, 3 June 2019 (UTC)
