When equal volumes of the following solutions are mixed, precipitation of `AgCI (K_(sp) = 1.8 xx 10^(-10))` will occur only wity

Options

A. `10^(-4) M (Ag^(+))` and `10^(-4)M(Cl^(-))`
B. `10^(-5)M (Ag^(+))` and `10^(-5)M (Cl^(-))`
C. `10^(-5)M (Ag^(+))` and `10^(-6)M (Cl^(-))`
D. `10^(-10) M (Ag^(+))` and `10^(-10) M (Cl^(-))`

Answer

A

Explanation

Ionic product ,` [Ag^(+)][Cl^(-)]` exceeds `K_(sp)` when `10^(-4)M (Ag^(+))` and `10^(-4)M(Cl^(-))` ions are mixed . Hence precipitated takes place.
