Talk:Hypophosphoric acid

error in formula

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

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.
