Ag_((s))|AgBr_((s))|Br^(-)(0.011M)||Cl^(-)(0.2M)|AgCl_((s))|Ag_((s)) if K_(sp) of AgBr & AgCl at 25^(@)C are 10^(-12) & 10^(10) respectively find which is/are true for above cell at 25^(@)C(log2=0.3)

Answer»

As `E_(Ag^(+)//Ag)^(@)` is not given so `E_("CELL")` cannot be determined
`E_("cell")` is `0.0413` volt
`/_\Glt0`
`E^(@)=0`

SOLUTION :`E_(cl^(-)//AgCl//Ag)^(@)=E_(Ag^(+)//Ag)^(@)+(RT)/F IN K_(sp)`………..(i)
`E_(Br^(-))^(@)//AgBr//Ag=E_(Ag^(+)//Ag)^(@)+(RT)/F In K_(sp)`…..(II)
as `E_(Ag^(+)//Ag)^(@)` will be cancelled onn subtractions (i) & (ii)
So `E_("cell")` can be determined
