In 1L saturated solution of AgCI [K(sp) ...

In 1L saturated solution of `AgCI [K_(sp) (AgCI) = 1.6 xx 10^(-10)], 0.1 mol` of `CuCI [K_(sp)(CuCI) = 1.0 xx 10^(-6)]` is added. The resultant concentration of `Ag^(+)` in the solution is `1.6 xx 10^(-x)`. The value of "x" is.

If is a case of simultaneous solubility of salts with a common ion. Here, solubility product of CuCl is much greater than of AgCl, it can be assumed that `Cl^(-)` in solution comes mainly from CuCl.
`[Cl^(-)] = sqrt(K_(sp)(CuCl)) = 10^(-3)M`
Now, for `AgCl, K_(sp) = 1.6 xx 10^(-10) = [Ag^(+)][Cl^(-)] = [Ag^(+)] xx 10^(-3)`
