In alkaline medium. MnO 4 - oxidises I - to

Options

  1. AIO 4 -
  2. BIO -
  3. CI 2
  4. DIO 3 -

Correct answer

D. IO 3 -

Step-by-step solution

In neutral or faintly alkaline solution the oxidation of iodide to iodate taken place with potassium permanganate. 2 MnO 4 - + H 2 O + I - → 2 MnO 2 + 2 OH - + IO 3 - In the above reaction MnO 4 - is an oxidising agent and I - is a reducing agent. Hence option D is the answer.
