The `emf` of a galvanic cell, with electrode potentials of silver `= + 0. 80 V` and that of copper `= + 0.34 V`, is .

A

` - 1.1 V`

B

` +1.1 V`2

C

` +0. 46 V`

D

` + 0. 76 V`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(cell)^@ = E_(Ag^+//Ag)^@ -E_(Cu//Cu^(2+)^@`
`=0.80 V- (0. 34 V) =0. 46 V`.
