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_2S` has - 2 oxidation state

B

S in `SO_2` has oxidation state + 4

C

Hydrogen in `H_2S` more +ve than oxygen

D

Oxygen is more – ve in `SO_2`

Text Solution

Verified by Experts

The correct Answer is:
A, B
In `H_2S` sulphur shows – 2 oxidation state and in `SO_2` shows + 4 oxidation state. Hence `SO_2` shows both oxidising and reducing properties.
