The emf `(E^(@))` of the following cels are :
`Ag|Ag^(+) (1 M)||Cu^(2+) (1 M)|Cu, E^(@)=-0.46` volt
`Zn|Zn^(2+) (1 M)||Cu^(2+) (1 M)|Cu, E^(@)=+1.10` volt
Calculate the emf of the cell :
`Zn|Zn^(2+) (1 M)||Ag^(+) (1 M)|Ag`

Text Solution

Verified by Experts

The correct Answer is:
1.56V
(i) `E_(Cu^(2+)//Cu)^(@)-E_(Ag^(+)//Ag)^(@)=-0.46V` ltBrgt (ii) `E_(Cu^(2+)//Cu)^(@)-E_(Zn^(2+)//Zn)^(@)=+1.10V`
Subtract (i) from (ii).
