In the depression of freezing point experiment
A. Vapour pressure of the solution is less than that of pure solvent
B. Vapour pressure of the solution is more than that of pure solvent
C. Only solute molecules solidify at the freezing point
D. Only solvent molecules solidify at the freezing point
Options:
Answer:
A
Solution:
Since the solute particles do not evaporate, the vapour pressure of the solution is lower than that of the pure solvent. The lowering of the vapour pressure depends on the number of solute particles that have been dissolved.
In the depression in freezing point experiment, it is found that the vapour pressure of a solution is less than that of pure solvent. Only solvent molecules solidify at freezing point.
