The standard reduction potentials of Cu^...

The standard reduction potentials of `Cu^(2+)//Cu` and `Cu^(2+)//Cu^(+)` are 0.337 V and 0.153V respectively. The standard electrode potential of `Cu^(+)//Cu` half-cell is

A

0.184V

B

0.827V

C

0.521Vq

D

0.490V.

Text Solution

Verified by Experts

The correct Answer is:
C
See A-Level information `(E_(Cu^(+)//Cu)^(@)=2E_(Cu^(2+)Cu^(2+)//Cu)-E_(Cu^(2+)//C u)=2xx0.337V-0.153V)`
`=0.674V-0.153V=0.521V`
