Given that the standard potential ` ( E ^(@)) ` of ` Cu ^(2 + ) //Cu and Cu ^( + ) //Cu ` are ` 0.34 V and 0.522V ` respectively, then ` E ^(@)` of ` Cu ^( 2 + )// Cu ^( + ) ` is :

A

`PgtSgtRgtQ`

B

`SgtRgtQgtP`

C

`RgtgtRgtP`

D

`QgtRgtSgtP`

Text Solution

Verified by Experts

The correct Answer is:
D
`Cu^(2+)+2e ^(-)rarrCu`
`E_("red")=E_("red")^(@)+(0.0591)/(2)"log"[Cu^(2+)]`
`therefore` greater is `Cu^(2+)` ion concentration, greater will be the reduction potential.
