Calculate the standard reduction potenti...

Calculate the standard reduction potential of `Ag^(+)|Ag` electrode when the cell potential for the cell ,
`Cu (s) |Cu^(2+) (1 M) || Ag^(+) (1 M) Ag` is 0.46 V . Given that `Cu^(2+) |Cu = 0.34` V

Text Solution

Verified by Experts

The correct Answer is:
0.80 V
`E_(Cell)^(Theta) = E_((Ag^(+) |Ag))^(Theta) - E_((Cu^(2+) |Cu))^(Theta)`
`0.46 = E_(Ag^(+) |Ag)^(Theta) = -0.34`
`therefore E_((Ag^(+)|Ag))^(Theta) = 0.80 V`
