What is the ratio of the weights liberated at the cathode when the same current is passed through two solutions of ferric and ferrous slats arranged in series for a given time interval

A

`3:2`

B

`2:3`

C

`1:3`

D

`3:1`

Text Solution

Verified by Experts

The correct Answer is:
B
`W_(Fe^(3+))/(W_(Fe^(2+))=("Equivalent weight of" Fe^(3+))/("Equivalent weight of" Fe^(2+))=(56//3)/(56//2)=2:3`
