The quantity electricity needed separately for the electrolysis of 1 M solution of ZnSO_(4), AlCl_(3) and AgNO_(3) completely is in the ratio of :

Answer»

`2:3:1`
`2:1:1`
`2:1:3`
`2:2:1`

Solution :(a) `Zn^(2+)+underset(2F)2e^(-) to underset(1mol)(Zn)`
`AL^(3+)+underset(3F)3e^(-) to underset(1mol)(Al)`
`Ag^(+)+underset(1F)e^(-) to underset(1 MOL)(Ag)`
The NUMBER of FARADAYS needed are in the ratio :
`2F:3F:1F "or" 2:3:1`.
