Which compound does not dissolve in acetic acid?

The solubility product $(K_{sp})$ for sodium chloride is $36 \text{ mol}^2/\text{L}^2$. The solubility of sodium chloride is:

Solubility product $(K_{sp})$ of salts of type $MX$,$MX_2$,and $M_3X$ at temperature $T$ are $4 \times 10^{-8}$,$3.2 \times 10^{-14}$,and $2.7 \times 10^{-15}$ respectively. The solubility of the salts at temperature $T$ are in the order:

The solubility product of salt $B_2A$ is $3.2 \times 10^{-11}$ at $298 \ K$. What is the solubility of the salt at the same temperature?

$A$ precipitate is formed when:

If the solubility product $K_{sp}$ of a sparingly soluble salt $MX_2$ at $25\,^{\circ}C$ is $1.0 \times 10^{-11}$,the solubility of the salt in $\text{mol L}^{-1}$ at this temperature will be:
