How much charge is required for the following reductions: i. 1 mol of `Al^3+` to `Al` ? ii. `1 ~mol` of `Cu^2 *` to `Cu ?` 1 ~mol ot MnO_4^- to Mn^2+

Explanation

i. The electrode reaction is
`A l^2 *+3 e^- Al`
.2uantity of charge required -for reduction ul. `1 ~mole` of `Al^3 *=3 xx F=3 xx 96.500`
- `quad C=289500 C`
ii. The elewude reaction is
`Cu^2++2 e^- Cu`
Quantity of chargé required for reduction of 1 . mole of `Cu^2 *=2 xx F=2 xx 96500 C=1.93 .000 C`
iii. The electrode reaction is `MnO_4^* Mn^2+`
