Question

How do the freezing point and boiling point of a solution compare with those of its pure solvent?The freezing point of the solution is _________a) higher b) lower and the boiling point is ________a) higherb) lowerthan that of its pure solvent.

Answer 1

Step-by-step explanation:

A solvent makes contact with other molecules and thereby increasing the Van der waals forces between the molecules. This in turn increases the freezing point of a solution.

The vapor pressure of solution is lower than that of a pure solvent. The boiling point is reached when the vapor pressure is raised to equal the atmospheric pressure.

Answer:

a) Higher

b) Higher
