How much charge is required for the following reductions :
1 mol of `MnO_(4)^(-)` to `Mn^(2+)` ?

Explanation

Electrode reduction : `MnO_(4)^(-)rarr Mn^(2+)`
i.e., `underset("1 mol")(Mn^(7+))+underset("5 mol")(5e)rarr Mn^(2+)`
`therefore` Quantity of charge required for the reduction of 1 mol of `Mn^(7+)=5F=5xx96500 C = 482500 C`
