What is the electrode potential of a gas...

What is the electrode potential of a gasous hydrogen electrode dipped in a solution `pH=5.0` relative to the calomel electrode with an electrode potential of `+0.28V` ?

A

`0.0125V`

B

`+0.575V`

C

`+0.015V`

D

`-0.575V`

Verified by Experts

The correct Answer is:

d

`E_(H_(2))=-0.059xx5=-0.295V`
`E_(calomel)=0.28V`
`E_(H_(2))` relative to the calomel electrode is
`=-0.295-0.28=-0.575V`
