For H 3 P O 3 and H 3 P O 4 the correct choice is Options: A . &nbspH3PO3 is dibasic and reducing B . &nbspH3PO3 is dibasic and non-reducing C . &nbspH3PO4 is tribasic and reducing D . &nbspH3PO3 is tribasic and non-reducing

For H3PO3 and H3PO4 the correct choice is

Question - For

H_{3} P O_{3}

and

H_{3} P O_{4}

the correct choice is

Options:

A . H3PO3 is dibasic and reducing

B . H3PO3 is dibasic and non-reducing

C . H3PO4 is tribasic and reducing

D . H3PO3 is tribasic and non-reducing

Answer: Option A
:
A

H - O - H | P ↓ O - O H

, it can donate two hydrogen ion, hence called dibasic. It is reducing as by releasing hydrogen it gets oxidised and reduceother.
