The equvalent mass of potassium permangn...

The equvalent mass of potassium permangnate in alkaline medium is
`MnO_(4)^(-) + 2H_(2)O + 3e^(-) to MnO_(2) + 4OH^(-)`

A

31.6

B

52.7

C

79

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
The reduction of the oxidising agent `MnO_(4)^(-)` involves gain of 3 electrons. Hence the equivalent mass=(Molar mass of `KMnO_(4)`/3=158.1/3=52.7
