h3po4 is trprotic while h3po3 is diprotic.why?

Answer 1

If H3PO4 is a triprotic acid while H3PO3 is diprotic, why? The structure of H 3 P O 4 is as under: 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 H 3 P O 3 is diprotic.

Answer 2
