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 0.41 V

D

decrease by 0.41 V

Text Solution

Verified by Experts

The correct Answer is:
D
`H^(+)+e^(-)to(1)/(2)H_(2),E=0-(0.0591)/(1)log_(10)((1)/([H^(+)]))=+0.591log_(10)[H^(+)]`
`E_(1)=0{pH=0}`
`E_(2)=+0.0591log_(10)[10^(-7)]=-0.0591xx7{atpH=7}=-0.41V`
