Calculate the potential of silver electrode in a saturated solution of `AgBr(K_(sp)=6xx10^(-13))` containing `0.1 M KB r . E^(c-)._(Ag^(o+)|Ag)=0.80V.`

Explanation

`K_(sp)=[Ag^(o+)][Br^(c-)]`
`[Ag^(o+)]=(K_(sp))/([Br^(c-)])=(6xx10^(-13))/(0.1)=6xx10^(-12)M`
`Ag^(o+)+e^(-) rarr Ag`
`E=E^(c-)-(0.059)/(1)log.(1)/([Ag^(o+)])`
`=0.80-0.059log .(1)/([6xx10^(-12)])`
`=0.80-0.59[log 10^(12)-log6]`
`=0.80-0.059[12-0.7782]`
`=0.80-0.059xx11.2218`
`=0.80-0.6662=0.138 `
