When equal volumes of following solution are mixed, precipitation of `AgCl` ?
`(K_(sp)=1.8xx10^(-10))` will occur only with

Options

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

Answer

A

Explanation

`K_(sp)=1.8xx10^(-10)`
`[Ag^(+)][Cl^(-)]=10^(-4)xx10^(-4)=10^(-8)`
`:. K_(sp_(AgCl))lt[Ag^(+)][Cl^(-)]`
