Standard electrode potential of ell H(2...

Standard electrode potential of ell `H_(2)|H^(+)||Ag^(+)|Ag` is `(Ag^(+)//Ag)^(@)=0.80 V`

A

`0.8 v`

B

`-0.8 V`

C

`-1.2 V`

D

`1.2 v`

Text Solution

Verified by Experts

The correct Answer is:
D
`E_(cell) =E_(cathode)-E_(anode)`
Given `E_(Ag^(+)//Ag)^(@)=0.80 V H_(2) |H^(+)||Ag^(+)|Ag`
`therefore` hydrogen is anode and silver is cathode
`E_(cell)=E_(c )-E_(A)`
=0.80 -0
=0.80 V
