For H(3)PO(3) and H(3)PO(4) the correct ...

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_(3)PO_(3)` is dibasic and can act as a reducing agent because the central atom (P) is not in its highest oxidation state. So oxidation of `H_(3)PO_(3)` is possible but it is not possible for `H_(3)PO_(4)`.
