KMnO_4 acts as an oxidising agent in alkaline medium. When alkaline KMnO_4 is treated with KI , iodide ion is oxidized to

Correct answer: (C) IO_3. KMnO_4 (as an oxidizing agent) 2 MnO_4^-+H, O+I^- arrow 2 MnO,+2 OH^-+IO_3^-

Q10 / 180 · KCET 2018 · Chemistry

\( \mathrm{KMnO}_{4} \) acts as an oxidising agent in alkaline medium. When alkaline \( \mathrm{KMnO}_{4} \) is treated
with \( \mathrm{KI} \), iodide ion is oxidized to

A
\( I_{2} \)
B
IO
Correct answer
C
\( \mathrm{IO}_{3} \)
D
\( I O_{4} \)

Solution

\( \mathrm{KMnO}_{4} \) (as an oxidizing agent) \( 2 \mathrm{MnO}_{4}^{-}+\mathrm{H}, \mathrm{O}+\mathrm{I}^{-} \rightarrow 2 \mathrm{MnO},+2 \mathrm{OH}^{-}+\mathrm{IO}_{3}^{-} \)

Hence, the correct answer is option: 'C'.
