If solubility product of $Z{r_3}{\left( {P{O_4}} \right)_4}$ is denoted by $K_{SP}$ and its molar solubility is denoted by $S$, then which of the following relation between $S$ and $K_{SP}$  is correct?

The solubility product of $AgCl$ is $4.0 \times {10^{ – 10}}$ at $298\,\,K.$ The solubility of $AgCl$ in $0.04\,m\,\,CaC{l_2}$ will be

$K_{sp}$ for $BaSO_4$ at $25\,^oC$ is $1.1 \times 10^{-10}$. To make the new solubility equal to $1.1 \times 10^{-8}$, it is necessary to use the solution of $Na_2SO_4$ of the following concentration….$M$

The solubility product of a sparingly soluble salt $A _{2} X _{3}$ is $1.1 \times 10^{-23}$. If specific conductance of the solution is $3 \times 10^{-5} \,S\, m ^{-1}$, the limiting molar conductivity of the solution is $x \times 10^{-3} \,S\, m ^{2}\, mol ^{-1}$. The value of $x$ is …

The solubility product of $Ag_2CO_3$ and $FeCO_3$ in water at $25\,^oC$ are $4 \times 10^{-12}$ and $2.5 \times 10^{-11}$ respectively. If $S_1$ and $S_2$ are their solubilities in water respectively when dissolved separately, then $S_1/S_2$ is
