The standard reduction potential for two reactions are given below `AgCl(s)+e^(-)rarrAg(s)+Cl^(-)(aq) ,E^(@)=0.22V` `Ag^(+)(aq)+e^(-)rarrAg(s),E^(@)=0.80V` The solubility product of AgCl under standard conditions of temperature is given byA. `1.6xx10^(-5)`B. `1.5xx10^(-8)`C. `3.2xx10^(-10)`D. ` 1.5xx10^(-10)`

Answer» Correct Answer - D
For the equilibrium
`AgCl(s)overset(H_(2)O)hArrAg^(+)(aq)+Cl^(-)(aq)`
`k_(sp)=[Ag^(+)][Cl^(-)]`
`AgCl(s)+e^(-)rarrAg(s)+Cl^(-)(aq)E^(@)=0.22V`
`Ag(s)rarrAg^(+)(aq)+e^(-),E^(@)=-0.80V`
`AgCl(s)rarrAg^(+)(aq)+Cl^(-)(aq)`
`E^(@)=(0.22-0.80)V`
`=-0.58V`
