The standard electrode potential of a me...

The standard electrode potential of a metal-metal ion `(Ag//Ag^(+))` and metal- sparingly soluble salt anion `(Ag|AgCl|Cl^(-))` are related as :

A

`E_(Ag^(+)|Ag)^(@)=E_(Cl^(-) |AgCl|Ag)^(@) + (RT)/(F) ln K_(sp)`

B

`E_(Cl^(-) | AgCl| Ag)^(@) = E_(Ag^(+)|Ag)^(@) + (RT)/(F) ln K_(sp)`

C

`E_(Cl^(-) | AgCl| Ag) ^(@) = E_(Ag^(+) | Ag)^(@) - (RT)/(F) ln ([Cl^(-1)])/(K_(sp))`

D

`E_(Cl^(-) ||AgCl|Ag)^(@) = E_(Ag^(+)|Ag)^(@) - (RT)/(F) ln (K_(sp))/([Cl^(-)])`

Text Solution

Verified by Experts

The correct Answer is:
B
`E_(Cl^(-))^(0)//AgCl // Ag = [E_(Ag^(+))^(0) // Ag^(+)""(RT)/(nF) ln K_p ]`
