How much charge is required for the following reductins?
(i) 1 mole of `AI^(+3) "to" AI`
(ii) 1 mole of `MnO_(4)^(-) "to" Mn^(+2)`

Text Solution

Verified by Experts

(i) `AI^(+3)+3e^(-)rarrAI`
Quantity of charge requried =3F
=3 `xx` 96500
=289500 C
(ii) `MnO_(4)^(-)+5e^(-1)rarrMn^(+2)`
Quantity of charge requried =5F
=5`xx`96500
=482500 C
