Vedclass · Answer

(B) When $HgI_2$ is added to an aqueous solution of $KI$,it reacts to form a soluble complex: $HgI_2 + 2KI \rightarrow K_2[HgI_4]$.
This reaction increases the total number of solute particles in the solution.
According to the colligative property,the depression of freezing point $(\Delta T_f)$ is directly proportional to the van't Hoff factor $(i)$ and the molality of the solution.
Since the number of particles increases,the freezing point of the solution decreases.
