How much volume of 0.185 N - `KMnO_(4)` solution would be needed for complete reaction with 25 ml of 0.212 N - `KNO_(2)` in acidic medium?

A

`57.29ml`

B

`11.46ml`

C

`28.65ml`

D

`22.92ml`

Text Solution

Verified by Experts

The correct Answer is:
C
Eq. `KMnO_(4)` = Eq. `KNO_(2)`
`0.185xxV=25xx0.212impliesV=28.6mL`
