The reduction potential of a hydrogen electrode at `pH 10` at `298K` is : `(p =1` atm)

A

`p(H_(2)) = 1 atm, [H^(+)] = 1M`

B

`p(H_(2)) = 1 atm, [H^(+)] = 2 M`

C

`p(H_(2)) = 2atm, [H^(+)] = 2M`

D

`p(H_(2)) = 2.5 atm, [H^(+)]=1.5 M`

Verified by Experts

The correct Answer is:

B

`E_(H^(+)//H_(2).pt) = -0.0591/n log (pH_(2))^(1//2)/[H^(+)]`
