Question:

KMnO₄ acts as an oxidising agent in acidic medium. When acidic KMnO₄ reacts with KI, then I^- gets converted to

Options:

IO₃^-

IO^-

I₂

IO₄^-

Correct Answer:

I₂

Explanation:

KMnO₄ acts as an oxidising agent in acidic medium. When acidic KMnO₄ reacts with KI, then I^- gets converted to I₂.

In acid solutions: Iodine is liberated from potassium iodide:

10I^– + 2MnO₄^– + 16H⁺ → 2Mn²⁺ + 8H₂O + 5I₂
