Chemistry - Salt Analysis Question with Solution | TestHub

Based on the Ksp values and salt analysis cation identification, we can say that order of Ksp value is:
$\mathrm{HgS}<\mathrm{PbS}<\mathrm{AgBr}<\mathrm{Ca}(\mathrm{OH}{)}_2$

K sp values
$\begin{array}{rl}& \mathrm{HgS}\to 4\times 10^{-53}\\ & \mathrm{PbS}\to 8\times 10^{-28}\\ & \mathrm{AgBr}\to 5\times 10^{-13}\\ & \mathrm{Ca}(\mathrm{OH}{)}_2\to 5.5\times 10^{-6}\end{array}$
