Question

Why is HCl not used to make the medium acidic in oxidation reactions of KMnO₄ in acidic medium?

(i) Both HCl and KMnO₄ act as oxidising agents.

(ii) KMnO₄ oxidises HCl into Cl₂ which is also an oxidising agent.

(iii) KMnO₄ is a weaker oxidising agent than HCl.

(iv) KMnO₄ acts as a reducing agent in the presence of HCl.

Answer 1

(ii) KMnO₄ oxidises HCl into Cl₂ which is also an oxidising agent.
