MCQ
The vapour pressure will be lowest for
- A$0.1 M$ sugar solution
- B$0.1 M KCl $ solution
- ✓$0.1 M$ $Cu{(N{O_3})_2}$solution
- D$0.1 M$ $AgN{O_3}$ solution
✓
Answer
Correct option: C.
$0.1 M$ $Cu{(N{O_3})_2}$solution
c
(c) Vapour pressure of a solvent is lowered by the presence of solute in it. Lowering in vapour pressure is a colligative property i.e., it depends on the no. of particles present in the solution. $Cu{(N{O_3})_2}$ give the maximum no. of ions. $(i.e., 3) $ so it causes the greatest lowering in vapour pressure of water.
