Updated the Dihydrogen phosphate article

I updated the lead section and added information about sources and uses of dihydrogen phosphate. As well I added some new information in the structure and acid-base equilibria sections. I added 5 new sources for the information I added and updated the bibliography. Mrothroc (talk)mrothroc — Preceding undated comment added 16:36, 23 March 2021 (UTC)[reply]

Thank you! Some suggestions:

Generally, Wikipedia presents facts. We avoid teaching and we give no advice (... are safe to consume... etc).
Wikipedia owes no allegience to the US. So "FDA" should be qualified as U.S. FDA. The U.S. FDA's information is probably well informed and maybe authoritative, but it is a US perspective.
ref numbers follow punctuation.
Formally, salts do not exist in solution, ions do. So Sodium dihydrogen phosphate does not exist in solution.
PubChem is not a very good source, but is an aggregator of sources. It is preferable to find the source.--Smokefoot (talk) 17:24, 23 March 2021 (UTC)[reply]

Suggestions

I suggest that you @Mrothroc: focus on the generic properties of the ion or its salts. In the use section: So for the uses mention the properties that cause it to be useful. Is it a fertilizer that has the correct pH. What form of ion do plants need? Is it a buffer in a mixture with another monohydrogen phosphate to ensure a pH? Is it causing an alkaline condition? You could write more about the structure of the ion, what are the angles and lengths of its bonds, and how does it differ to the other phosphate ions. What structures does it adopt in the solid state? What happens in a molten state? In particular as a flux to dissolve inorganic stuff. (I think this may be important in mineral tests). I would also like to see a comparison with Difluorophosphate, and hydrogensulfate as those ions are isoelectronic. Graeme Bartlett (talk) 22:23, 23 March 2021 (UTC)[reply]
