Arrange the following in increasing order of solubility product :
$\mathrm{Ca}(\mathrm{OH})_2, \mathrm{AgBr}, \mathrm{PbS}, \mathrm{HgS}$
Solution
<p>Based on the Ksp values and salt analysis cation identification, we can say that order of Ksp value is:</p>
<p>$\mathrm{HgS}<\mathrm{PbS}<\mathrm{AgBr}<\mathrm{Ca}(\mathrm{OH})_2$</p>
<p>Ksp values</p>
<p>$$\begin{aligned}
& \mathrm{HgS} \rightarrow 4 \times 10^{-53} \\
& \mathrm{PbS} \rightarrow 8 \times 10^{-28} \\
& \mathrm{AgBr} \rightarrow 5 \times 10^{-13} \\
& \mathrm{Ca}(\mathrm{OH})_2 \rightarrow 5.5 \times 10^{-6}
\end{aligned}$$</p>
