Question
Which of the following statements is correct ?
A.
A saturated solution will remain saturated at all temperatures.
B.
A plant cell swells when placed in hypertonic solution.
C.
The depression in freezing point is directly proportional to molality of the solution.
D.
Lowering in vapour pressure is a colligative property.
Answer :
The depression in freezing point is directly proportional to molality of the solution.
Solution :
Solubility changes with temperature. A plant cell shrinks in hypertonic solution. Relative lowering of vapour pressure is a colligative property.
