On passing 3 faraday of electricity through the three electrolytic cells connected in series containing `Ag^+`, `Ca^(2+)` and `Al^(3+)` ions respectively. The molar ratio in which the three metal ions are liberated at the electron is

A

`1:2:3`

B

`2:3:1`

C

`6:3:2`

D

`3:4:2`

Text Solution

Verified by Experts

The correct Answer is:
c
`1Eq` of `Ag^(o+):1Eq` of `Ca^(2+):1Eq` of `Al^(3+)`
`1 mol ofAg^(o+),(1)/(2)molof Ca^(2+),(1)/(3)mol of Al^(3+)`
`:. mol ` ratio i s`1:(1)/(2):(1)/(3)=6:3:2`
