Standard electrode potential of cell H2...

Standard electrode potential of cell ` H_2 ||H^+ || Ag^+ | Ag ` is ,.

A

` 1.2 V`

B

` -0.20 V`

C

`-1.2 V`

D

` 0.8 V`

Text Solution

Verified by Experts

The correct Answer is:
D
`1/2 H_2 |H^+||Ag^+|Ag|`
` E_("cell")^@ =E_("cathode")^@-E_("Anode")^@ =E_(Ag^(+)//Ag)^@ -E_(H^(+)//1/2H_2)^@`
` (0.80) - (0.0) = 0.80 V`.
