In the reaction `H_(2)S + H_(2)O_(2) rarr S + 2H_(2)O`

A

`H_(2)S` is an acid and `H_(2)O_(2)` is a base

B

`H_(2)S` is a base and `H_(2)O_(2)` is an acid

C

`H_(2)S` is an oxidising agent and `H_(2)O_(2)` is a reducing agent

D

`H_(2)S` is a reducing agent and `H_(2)O_(2)` is an oxidising agent

Text Solution

Verified by Experts

The correct Answer is:
D

Here, the oxidation number of S increases from -2 in `H_(2)S` to 0 in elemental sulphur, while that of O decreases from -1 in `H_(2)O_(2)` to -2 in `H_(2)O`, therefore `H_(2)S` is a reducing agent and `H_(2)O_(2)` is an oxidising agent.
