The equivalent mass of potassium permanganate in alkaline medium is its :

A

Molar mass/5

B

Molar mass/3

C

Molar mass/2

D

Molar mass/1

Text Solution

Verified by Experts

The correct Answer is:
D
In alkaline medium,
`2KMnO_(4)+2KOHrarr2K_(2)MnO_(4)+H_(2)O+O`
Ionic equation `MnO_(4)^(-)+e^(-)rarr MnO_(4)^(2-)`
`:.` Eq. wt. of `KMnO_(4)` = Molar mass/1.
