Question

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 :

Accepted Answer

Option C. In the depression of freezing point experiment
only solvent molecules solidify and vapour pressure of
solution decreases as some of the surface area is occupied
by solute molecules, so less number of molecules will go in
vapour form.
