$A$ precipitate of $CaF_2$ $(K_{sp} = 1.7 \times 10^{-10})$ will be obtained when equal volumes of the following are mixed:

The solubility product for a salt of the type $AB$ is $4 \times 10^{-8}$. What is the molarity of its saturated solution?

Find the solubility of $PbI_2$ if its solubility product is $7.0 \times 10^{-9}$.

Select the ion exchange reaction,which proceeds in the forward direction in an aqueous medium.

Assign $A$,$B$,$C$,$D$ from the given type of reaction.
$BaSO_3 \downarrow + SO_2 + H_2O \longrightarrow Ba(HSO_3)_2$

In qualitative analysis,the metals of group $I$ can be separated from other ions by precipitating them as chloride salts. $A$ solution initially contains $Ag^{+}$ and $Pb^{2+}$ at a concentration of $0.10 \, M$. Aqueous $HCl$ is added to this solution until the $Cl^{-}$ concentration is $0.10 \, M$. What will the concentrations of $Ag^{+}$ and $Pb^{2+}$ be at equilibrium? ($K_{sp}$ for $AgCl = 1.8 \times 10^{-10}$,$K_{sp}$ for $PbCl_2 = 1.7 \times 10^{-5}$)
