In which of the following reactions, `H_(2)O_(2)` acts as a reducing agent?

A

`PbO_(2)(s)+H_(2)O_(2)(aq)toPbO(s)+H_(2)O(l)+O_(2)(g)`

B

`Na_(2)SO_(3)(aq)+H_(2)O_(2)(aq)toNa_(2)SO_(4)(aq)+H_(2)O(l)`

C

`2KI(aq)+H_(2)O_(2)(aq)to2KOH(aq)+I_(2)(s)`

D

`KNO_(2)(aq)+H_(2)O_(2)(aq)toKNO_(2)(aq)+H_(2)O(l)`

Text Solution

Verified by Experts

The correct Answer is:
A
`PbO_(2)toPbO` (change in O.S. is +4 to +2 hence reduction).
