25. When mercuric iodide is added to the aqueous solution of potassium iodide
(1987, 2M)
(a) freezing point is lowered
(b) freezing point is lowered
(c) freezing point does not change
(d) boiling point does not change
Show Answer
Answer:
Correct Answer: 25. (a)
Solution:
Addition of $\mathrm{HgI}_2$ to $KI$ solution establishes the following equilibrium :
$ \mathrm{HgI}_2+2 \mathrm{KI} \rightleftharpoons \mathrm{K}_2\left[\mathrm{HgI}_4\right] $
The above equilibrium decreases the number of ions ( $4$ ions on left side of reaction becomes three ions on right side), hence lowers the freezing point.
