MCQ
When $HgI_2$ is added to aqueous solution of $KI$, then the
- ✓Freezing Point is raised
- BFreezing Point is lowered
- CFreezing Point does not change
- DBoiling 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.
