MCQ
When $HgI_2$ is added to aqueous solution of $KI$, then the
  • Freezing Point is raised
  • B
    Freezing Point is lowered
  • C
    Freezing Point does not change
  • D
    Boiling Point does not change

Answer

Correct option: A.
Freezing Point is raised
a
$HgI_2 + 2KI \to  K_2[HgI_4]$ In solution no. of particles decreases therefore $\Delta T_f$ decreases and freezing point of solution is increased.
