The emf of the cell: Cu(s)|Cu^(2+) (1M...

The emf of the cell:
`Cu(s)|Cu^(2+) (1M)||Ag^(+)(1M)|Ag`
is 0.46V. The standard reduction potential for `Ag^(+)//Ag` is 0.80V. The standard reduction potential of `Cu^(2+)//Cu` is:

A

-0.34

B

1.26

C

-1.26

D

0.34

Text Solution

Verified by Experts

The correct Answer is:
D
`E_("cell") = E_("red") - E_("ox")`
`0.463 = 0.800 - E_(Cu)`
`E_("Cu) = 0.337 V`
