When `0.1 mol MnO_(4)^(2-)` is oxidized the quantity of electricity required to completely oxidize `MnO_(4)^(2-)` to `MnO_(4)^(-)` is

Options

A. 96500 C
B. `2 xx 96500 C `
C. 9650 C
D. 96.50 C

Answer

C

Explanation

Change in oxidation number from `MnO_(4)^(2-)` to `MnO_(4)^(-)` is from +6 to +7 . Therefore , 1 electron is lost in the process .
Charge required by 1 mol `MnO_(4)^(2-) = 1 F `
Charge required by 0.1 mol `MnO_(4)^(2-) = 0.1` F
= 9650 C
