How much will the reduction potential of a hydrogen electrode change when its solution initially at `pH=0` is neutralized to `pH=7` ?

A

Increase by `0.059V`

B

Decrease by `0.059V`

C

Increase by `0.41V`

D

Decrease by `0.41V`

Text Solution

Verified by Experts

The correct Answer is:
d
`(E_(H^(o+)|H_(2)))_(1)=-0.059pH_(1)=0`
and `(E_(H^(o+)|H_(2)))_(2)=-0.059xx7=-0.41V`
