correct order of acidic strength H3PO4,H3PO3,H3PO2
Answers (3)
The order is h3po2>h3po3>h3po4 all this happens because of cross conjugation of the lone pair of e of the oxygen atoms having hydrogen and the doubly bonded oxygen atom ..

Hello aspirant
Order of acidic strength ( acidic character) among H3PO4, H3PO3 and H3PO2 is
H3PO4 ( pka 2.1) < H3PO3 ( pka 1.5) < H3PO2 ( pka 1.3)
The acidic character of oxyacids of same elements which is in different oxidation state increases with the increase if it's oxidation state. Also number of P - OH bond increases the acidity of species decreases

No. Of OH bond in H3PO3 is more than that og H3PO2.Then, why acidic strength of H2PO2 is more???????
