Number of coulombs of current required to convert completely 1 mole of `MnO_(4)^(-)` ions in acid medium to one mole of `Mn^(2+)` ions electrolytically is

A

96500

B

`5 xx 96500`

C

`96500 xx 2`

D

`96500 xx 6`

Verified by Experts

The correct Answer is:

B

`overset(MnO_(4)^(-))(+7) to overset(Mn^(2+))(+2)`
Changes in O.S. =5
Current required = 5F
