Calculate the emf of the following concentration cell at `25^(@)C`:
`Ag(s)|AgNO_(3) (0.01 M)||AgNO_(3) (0.05 M)|Ag (s)`

A

`-0.414 V`

B

`0.828 V`

C

`0.414 V`

D

`0.0414 V`

Text Solution

Verified by Experts

The correct Answer is:
D
`E=E^(@)-0.0591/n log_(10) Q`
`( :' E^(@)=0" for all concentration cells")`
`0-0.0591/1 log_(10) (0.01/0.05)=0.0414 V`
