KMnO4KMnO_{4} acts as an oxidizing agent in alkaline medium when alkaline KMnO4KMnO_{4} is treated with KI, iodide ion is oxidized to

A

I2I_{2}

B

IO−IO^{-}

C

IO3−IO_{3}^{-}

D

IO4−IO_{4}^{-}

Answer

IO3−IO_{3}^{-}

Explanation

Solution

2MnO4−+H2O+I−→2MnO2+2OH−+IO3−2MnO_{4}^{-} + H_{2}O + I^{-}\overset{\quad\quad}{\rightarrow}2MnO_{2} + 2OH^{-} + IO_{3}^{-}
