The equivalent weight of`KMnO_(4)` (formula weight M) when it is used as an oxidant in neural medium is

A

M

B

`M/2`

C

`M/3`

D

`M/5`

Text Solution

Verified by Experts

The correct Answer is:
C
In neutral medium
`MnO_4^(-) + 2H_2O + 3e^(-) to MnO_2 + 4OH^(-)`
`therefore `Equivalent weight is `"Molecular weight"/3`
