Find the number of coulombs required for...

Find the number of coulombs required for conversion of one mole of `MnO_(4)^(-)` to one mole of `Mn^(2+)`.

A

96500

B

95600

C

`96500xx5`

D

`96599xx7`

Text Solution

Verified by Experts

`overset(+7)(Mn)O_(4)^(-) rarr Mn^(2+)`
Change in oxidation number = 5 ( 1//2)
The number of Coulombs required for the conversion of one mole of `MnO_(4)^(-)` to `Mn^(2+) = 5 xx 96500 `. ( 1//2)
