On reduction of `KMnO_(4)` by oxalic acid in acidic medium, the oxidation number of Mn changes.What is the magnitude of this change ?

A

From 7 to 2

B

From 6 to 2

C

From 5 to 2

D

From 7 to 4

Text Solution

Verified by Experts

The correct Answer is:
A
In acid medium `MnO_(4)^(-)` changes to `Mn^(2+)`, hence O.N. changes from `+7` to `+2`.
