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
Choose the most appropriate answer from the options given below:
A and C only
A only
A and D only
B and C only
On adding non-volatile solute to pure solvent, depression in freezing point and lowering in vapour pressure occurs.
