`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 acid than HCl

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
HCl is oxidized by `KMnO_(4)` to `Cl_(2)`
`2KMnO_(4)+16HClrarr2KCl+2MnCl_(2)+8H_(2)O+5Cl_(2)`.
