Let the solubility of an aqueous solution of $Mg(OH)_2$ be $x$,then its $K_{sp}$ is:

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?

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

For a sparingly soluble salt $A_pB_q$,the relationship of its solubility product $(L_S)$ with its solubility $(S)$ is

The ionization constant of benzoic acid is $6.46 \times 10^{-5}$ and $K_{sp}$ for silver benzoate is $2.5 \times 10^{-13}$. How many times is silver benzoate more soluble in a buffer of $pH$ $3.19$ compared to its solubility in pure water?

If the ${K_{sp}}$ for $HgSO_4$ is $6.4 \times 10^{-5}$,then the solubility of the salt is:
