At `25^@C`, the potential (e.m.f) for the cell, `Al_((s))|Al_((aq))^(+3)(0.1 M)||Cd_((aq))^(+2)(0.01M)|Cd_((s))` is :-

A

1.36 volt

B

1.22 volt

C

–1.26 volt

D

–1.22 volt

Text Solution

Verified by Experts

The correct Answer is:
B
`therefore E_"cell"=(1.66-0.40)-0.06/6"log"[[Al^(+3)]^2]/[[Cd^(+2)]^3]`
`E_"cell"`=1.22 volt
