1.

The quantity of electricity needed to separately electrolyse 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 :`Zn^(2+) (1 M) + 2E^(-e) RARR Zn , 2 ` Faraday
`Al^(3+)(1 M) + 3 e^(-) rarr AI , 3` Faraday
`Ag^(+)(1 M) + e^(-) rarr Ag ,1` Farady
Ration of quantity of electricity required `=2:3:1`
