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

Answer»

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

Solution :`E_(Cl^(-))^(0)//AgCl // Ag = [E_(Ag^(+))^(0) // Ag^(+)""(RT)/(NF) ln K_p ]`
