Why HCl not used to make the mdeium acidic in oxidation reactions of `KMnO_(4)` in acidic medium ?

A

Both HCl and `KMnO_4` act as oxidising agents

B

`KMnO_4` oxidises HCl into `Cl_2` which is also an oxidising agent

C

`KMnO_4` is a weaker oxidising agent than HCl

D

`KMnO_4` acts as a reducing agent in the presence of HCl

Text Solution

Verified by Experts

The correct Answer is:
B
HCl is not used to make the medium acidic in oxidation reactions of `KMnO_4` in acidic medium. The reason is that if HCl is used, the oxygen produced from `KMnO_4 + HCl` is partly utilised in oxidising HCl to , Cl which itself acts as an oxidising agent and partly oxidises the reducing agent.
