Two electrolytic cells, one containing acidified ferrous sulphate and another acidified ferric chloride, are in series. The ratio of masses of Iron deposited at the cathode in the two cells will be

A

`2:1`

B

`2:3`

C

`1:1`

D

`3:2`

Text Solution

Verified by Experts

The correct Answer is:
D
`underset("Ferrous")(Fe^(++) + e^(-) to Fe) " "underset("Ferric")(Fe^(+3) + 3e^(-) to Fe)`
`2e^(-) xx 3 : 3e^(-) xx 2 therefore 3:2`
