In the chemical reaction `Cl_(2)+H_(2)S rarr 2HCl + S`, the oxidation number of sulphur changes from

A

`0` to `2`

B

`-2` to `0`

C

`2` to`0`

D

`-2` to `-1`

Text Solution

Verified by Experts

The correct Answer is:
B
Oxidation state of sulphur in `H_(2)S` is `-2`, while it is zero in `'S'`, i.e., in this reaction oxidation of sulphur and reduction of chlorine is takes place.
