Question

In order to completely oxidize `0.1 mol` of `MnO_(4)^(2-)` to permanganate ion. The quantity of electricity required is
A. `96500C`
B. `2xx96500C`
C. `9650C`
D. `96.50C`

Answer 1

Correct Answer - c
`MnO_(4)^(2-)rarr MnO_(4)^(c-)+e^(-)`
`1F=1mol `of `MnO_(4)^(c-)`
` 0.1F=0.1 mol` of `MnO_(4)^(c-)`
`0.1F=0.1xx96500=9650C`
