If `M` is the molecular weight of `KMnO_(4)`, its equivalent weight will be when it is converted into `K_(2)MnO_(4)`

A

`M`

B

`M//3`

C

`M//5`

D

`M//7`

Text Solution

Verified by Experts

The correct Answer is:
A
`2KMnO_(4)+2KOHto2K_(2)MnO_(4)+H_(2)O+[O]`
or `Moverset(+7)(n)O_(4)^(-)+e^(-)to overset(+6)(Mn)O_(4)^(2-)`
`:.` Eq. mass `=("Mol. Mass")/("Change in O.N.")=(M)/(1)=M`
