When mercuric iodide is added to the aqueous solution of KI, then the :

A

freezing point is raised

B

freezing point is lowered

C

freezing point does not change

D

boiling point does not change

Text Solution

Verified by Experts

When we add a complex is formed `HgI_(2)`, a complex `K_(2)[HgI_(4)]` is formed `2KI+HgI_(2)toK_(2)[HgI_(4)]`.
It results in a decrease in number of moles of particles, because of its `DeltaT_(f)` increases.
