The equivalent mass of postassium perman...

The equivalent mass of postassium permanganate 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 reaction of the oxidising agent `(MnO_(4)^(-))` involves gain of 3 electrons .
Hence of equivalent mass `= ("Molar mass of " KMnO_4)/(3)=(158.1)/(3)=52.7`.
