In alkaline medium. MnO _ 4 ^ - oxidises I ^ - to

In alkaline medium. MnO4−{MnO}_{4}^{-} oxidises I−{I}^{-} to

Options

  1. AIO4−{IO}_{4}^{-}
  2. BIO−{IO}^{-}
  3. CI2{I}_{2}
  4. DIO3−{IO}_{3}^{-}

Correct answer

D. IO3−{IO}_{3}^{-}

Step-by-step solution

In neutral or faintly alkaline solution the oxidation of iodide to iodate taken place with potassium permanganate.

2MnO4−+H2O+I−→2MnO2+2OH−+IO3−2{MnO}_{4}^{-} + {H}_{2}O + {I}^{-} \to 2{MnO}_{2} + 2{OH}^{-} + {IO}_{3}^{-}In the above reaction MnO4−{MnO}_{4}^{-} is an oxidising agent and I−{I}^{-} is a reducing agent. 

Hence option D is the answer.
