why h3po3 is diprotic ,h3po4 is triprotic,H3po2 is monoprotic acid? explain.

Explanation:

Due to more electronegativity difference between H and O, the H atom attached to O is detached rather than the H attached to P. So, when H3PO3 is added to water, only 2H+ ions are released. And that's why H3PO3 is a diprotic or dibasic acid.

Here there are 3 H atoms connected to 3 O atoms.These atoms are converted into ions by donating 1 electron to Oxygen as Oxygen has more electronegativity than hydrogen. Thus is triprotic because it can release 3 ions.

H3po2 behave as a monoprotic acid because it donates only one proton or hydrogen atom per molecule in aqueous solution. Hypo phosphorous acid is an acid as it dissolves in water to form hydrogen ions.
