Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
$P b C l_{2}$ is for more soluble than the $c h l o r i d e s$ of the other two ions, especially in hot water. This isthe reason why $H C l$ in concentrations which completely precipitate $H g_{2}^{2 +}$ and $A g^{+}$ may not be sufficient to do the same to $P b^{+ 2}$ .
Also, $P C l_{2}$ is unsoluble in the hot water.
