For the precipitation reaction of $Ag^{\oplus}$ ions with $NaCl,$ which of the following statements is true?

The $K_{sp}$ of an electrolyte $AB$ is $1 \times 10^{-10}$. If $[A^{+}] = 10^{-5} \ M$,which concentration of $B^{-}$ will not result in the precipitation of $AB$?

In a saturated solution of the sparingly soluble strong electrolyte $AgIO_3$ (molecular mass $= 283$),the equilibrium which sets in is $AgIO_{3(s)} \rightleftharpoons Ag^+_{(aq)} + IO^-_{3(aq)}$. If the solubility product constant $K_{sp}$ of $AgIO_3$ at a given temperature is $1.0 \times 10^{-8}$,what is the mass of $AgIO_3$ contained in $100 \ mL$ of its saturated solution?

The solubility of $PbCl_2$ is equal to .......

The solubility of $CaF_2$ in a solution of $0.1 \ M \ Ca(NO_3)_2$ is.

The value of $K_{sp}$ for $B_2CO_3$ is $3.2 \times 10^{-5}$. The concentration of $B^{+}$ in its saturated solution is :-
