Question

In neutral medium potassium permanganate oxidizes \( I^- \) to \( X \). Identify \( X \).

• A. Iodine
• B. Iodate
• C. Per iodate
• D. Hypo iodite

Hint:

Potassium permanganate oxidizes iodide to iodate in neutral medium and to iodine in acidic medium.

Answer 1

The Correct Option is B

Step 1: Oxidation of Iodide by \( KMnO_4 \) In a neutral medium, potassium permanganate oxidizes iodide (\( I^- \)) to iodate (\( IO_3^- \)). The reaction is: \[ 2MnO_4^- + I^- + H_2O \rightarrow 2MnO_2 + IO_3^- + 2OH^- \] Step 2: Identifying the Oxidation Product The product of oxidation is iodate (\( IO_3^- \)), making option (2) correct.
