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^(-4) M Ag^(+) and 10^(-6) M Cl^(-)`
C. `10^(-4) M Ag^(+) and 10^(-7) M Cl^(-)`
D. `10^(-4) M Ag^(+) and 10^(-5) M Cl^(-)`

Answer

A

Explanation

`K_(SP)=[Ag^(+)][Cl^(-)]` to get PPt ionic prodct` gt K_(SP)`
`1.8xx10^(-10)=10^(-4)x10^(-4)=10^(-8)`
`10^(-8) gt 1.8xx10^(-10)`
