हिन्दीIn the neutral or faintly alkaline medium, \( \text{KMnO}_4 \) oxidises iodide into iodate. The change in oxidation state of manganese in this reaction is from ________.
Correct answer · Option 3
+7 to +4
Explanation
In neutral or faintly alkaline medium, \( \text{KMnO}_4 \) is reduced to \( \text{MnO}_2 \). The oxidation state of Mn changes from +7 in \( \text{MnO}_4^- \) to +4 in \( \text{MnO}_2 \).
