In volumetric experiment, it was found that a solution of `KMnO_(4)` is reduced to `MnSO_(4)`. If the normality of solution is 1 N, then molarity of solution will be :

A

0.5 M

B

0.2 M

C

1 M

D

0.4 M

Text Solution

Verified by Experts

The correct Answer is:
B
Normality=Molarity `xx` Change in oxidation number
`overset(+7)(KMnO_(4)) to overset(+2)(MnSO_(4))`
Change in oxidation number=5
`therefore N=Mxx5`
`1=Mxx5`
M=0.2
