\( \mathrm{KMnO}_{4} \) 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
- C \( \mathrm{IO}_{3} \)
- D \( I O_{4} \)
Answer & Solution
Correct Answer
(C) \( \mathrm{IO}_{3} \)
Step-by-step Solution
Detailed explanation
\( \mathrm{KMnO}_{4} \) (as an oxidizing agent) \( 2 \mathrm{MnO}_{4}^{-}+\mathrm{H}, \mathrm{O}+\mathrm{I}^{-} \rightarrow 2 \mathrm{MnO},+2 \mathrm{OH}^{-}+\mathrm{IO}_{3}^{-} \)
