The equivalent mass of `KMnO_4`in the following reaction is ________________.
(M = Molecular mass)
`MnO_4^- +5Fe^(2+) + 8H^+ to Mn^(2+) + 5 Fe^(3+) + 4H_2 O`

A

`M/2`

B

`M/3`

C

`M/4`

D

`M/5`

Text Solution

Verified by Experts

The correct Answer is:
D
Here, equivalent weight of salt = `("Molecular weight")/("Number of electron lost or gained")`
Number of electron or gained =5
equivalent mass `=M/5`
