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

Options

A. Increase by `0.059V`
B. Decrease by `0.059V`
C. Increase by `0.41V`
D. Decrease by `0.41V`

Answer

d

Explanation

`(E_(H^(o+)|H_(2)))_(1)=-0.059pH_(1)=0`
and `(E_(H^(o+)|H_(2)))_(2)=-0.059xx7=-0.41V`
