If the $K_{sp}$ of $AgCl$ is $10^{-10}$,what is the volume of the solution required to prepare a saturated solution of $1.43 \ g$ of $AgCl$? $[M.W. = 143]$

Which of the following is the least soluble carbonate?

The solubility product of $PbCl_2$ at $20 \, ^oC$ is $1.5 \times 10^{-4}$. Calculate the solubility.

Assertion : $BaCO_3$ is more soluble in $HNO_3$ than in plain water.
Reason : Carbonate is a weak base and reacts with the $H^+$ from the strong acid,causing the barium salt to dissociate.

Which one of the following arrangements represents the correct order of solubilities of sparingly soluble salts $Hg_2Cl_2$,$Cr_2(SO_4)_3$,$BaSO_4$ and $CrCl_3$ respectively?

Solubility product constants $(K_{sp})$ of silver salts are given as $AgCl = 2 \times 10^{-10}$,$AgBr = 5 \times 10^{-13}$,$Ag_2CO_3 = 8 \times 10^{-12}$,and $AgI = 8 \times 10^{-17}$. Which salt shows the highest solubility?
