`KMnO_(4)` is a strong oxidising agent in acidic medium. To provide acidic medium `H_(2)SO_(4)` is used instead of HCl. This is because

A

`H_(2)SO_(4)` is a stronger oxidising agent than HCl

B

HCl is oxidised by `KMnO_(4)` to `Cl_(2)`

C

`H_(2)SO_(4)` is dibasic acid

D

Rate of reaction is faster in the presence of `H_(2)SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `KMnO_(4)` initially oxidises HCl to `Cl_(2)` and can then act as oxidising agent
`2HCl+(O) to H_(2)O+Cl_(2)`
Therefore, `H_(2)SO_(4)` is preferred to HCl in providing acidic medium.
