What sort of acid is phosphoric acid in aqueous solution?

Answer 1

Cameron Andrews

Cameron Andrews

Because the parent acid is potentially triprotic.............and phosphate salts, i.e. salts of #PO_4^(3-)# are possible.

I write #"potentially"# because in aqueous solution, phosphoric acid is to all intents and purposes, a diacid:

#H_3PO_4(aq) + 2KOH(aq) rarr K_2HPO_4(aq) + 2H_2O(l)#,

i.e. the salt is potassium biphosphate, #K_2^(+)[HPO_4]^(2-)#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
