For `H_(3)PO_(3)` and `H_(3)PO_(4)` the correct choice is

A

`H_(3)PO_(3)` is dibasic and reducing

B

`H_(3)PO_(3)` is dibasic and non-reducing

C

`H_(3)PO_(4)` is tribasic and reducing

D

`H_(3)PO_(3)` is tribasic and non-reducing

Text Solution

Verified by Experts

The correct Answer is:
A
`H-O-overset(H)overset(|)underset(O)underset(darr)P-OH`, Hence it is dibasic. It acts as reducing agent also.
