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

A

both HCl and `KMnO_(4)` actas oxidising agents.

B

`KMnO_(4)` oxidises HCl into `Cl_(2)`, which is also an oxidising agent.

C

`KMnO_(4)` is 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
`KMnO_(4)` oxidises HCl to `Cl_(2)`. `2KMnO_(4)+16HCl rarr 2KCl + 2MnCl_(2)+5Cl_(2)+8H_(2)O`
