ChemistryNEET 2022Potassium dichromate and permanganate

The d- and f-Block Elements

In neutral or faintly alkaline medium, $KMn O_{4}$ oxidises iodide into iodate. The change in oxidation state of manganese in this reaction is from:

B.+7 to +4✓
C.+6 to +4
D.+7 to +3

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
