The standard reduction potential for `Cu^(2+)|Cu` is `+0.34V`. Calculate the reduction potential at`pH=14` for the above couple . `K_(sp)` of `Cu(OH)_(2)` is `1.0xx10^(-19)`

A

`-0.2205V`

B

`+0.2205V`

C

`-0.11V`

D

`+0.11V`

Text Solution

Verified by Experts

The correct Answer is:
A
`[Cu^(2+)]=(K_(sp))/([OH^(-)]^(2))`
`E_(RP)=E_(RP)^(0)+(0.059)/(2)log_(10)[Cu^(2+)]`
