Talk:Hypophosphoric acid

error in formula[edit]

One of the formulas in the list of salts is wrong - K₃H₃P₂O₆.3H₂O. One of the "3"s is too much, but I cannot say which. In can either be

K₃HP₂O₆.3H₂O or
KH₃P₂O₆.3H₂O.

Does somebody know which of these two is known? I only saw the formula and thought, three potassium plus three hydrogen is too much... --79.243.235.231 (talk) 18:59, 29 April 2014 (UTC)[reply]

confusing text[edit]

In the top paragraph, it says "phosphorus atoms, one of which has a directly bonded H atom and an oxidation state of +3, which is joined by a P−O−P bridge to the second phosphorus atom which has an oxidation state of +5.". What on this Earth is this? I don't see any P-H bond, nor any P-O-P bridge in the hypophosphoric acid molecule. The sentence should be deleted. And in the Structure section says "Hypophosphorus acid contains oxonium ions and is best formulated [H₃O⁺]₂ [H₂P₂O₆]²⁻.". The formula of the acid and the whole sentence is false. The compound is a dioxonium dihydrogen hypophosphate, not hypophosphoric acid. Confusing anhydrous hypophosphoric acid and its hydrate or dioxonium salt is wrong, because the compounds are not the same, as well as confusing an-ammonious hypophosphoric acid and its ammoniacate or diammonium salt is wrong because the compounds are not the same as well.

Random accidental removal or vandalism that nobody noticed for over two months:( All fixed. DMacks (talk) 07:00, 30 July 2020 (UTC)[reply]

in the top paragraph the compound that the sentence is referring to is Isohypophosphoric acid not hypophosphoric acid. 2409:40C4:3C:A5AE:F16C:4DD2:807F:82B1 (talk) 18:34, 17 May 2024 (UTC)[reply]
