H(2)S acts only as reducing agent while ...

`H_(2)S` acts only as reducing agent while `SO_(2)` can act both as a reducing agent and as an oxidising agent. How will you account for it ?

A

S in`H_(2)` has –2 oxidation state

B

S in`SO_(2)` has oxidation state +4

C

Hydrogen in `H_(2)S`is more positive than oxygen

D

Oxygen is more negative in `SO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
AB
In `H_(2)S` sulphur shows –2 oxidation state and in `SO_(2)` shows oxidation state. Hence`SO_(2)` shows both oxidising and reducing properties.
