In acidic medium one mole of `MnO_(4)^(-)` accepts how many moles of electrons in a redox process?

A

1

B

3

C

5

D

6

Text Solution

Verified by Experts

The correct Answer is:
C
Oxidation state of `Mn` changes from `+ 7` and `+ 2` in acidic medium i.e. one mole of it accepts 5 mole of electrons.

    Assertion :- Equivalent weight of KMnO_(4) in acidic medium is M//5 (M=molecular weight) while in basic medium, it is equal of M/3. Reason :- In acidic medium, 1 mol of MnO_(4)^(-) gains 5 mole electrons while in basic medium it gains 3 mole electrons.
