Which of the following statements about the freezing point of a solution compared to the pure solvent is correct?
The freezing point of a solution is higher than that of the pure solvent.
A solution will freeze when its vapour pressure equals that of the pure solid solvent.
The presence of a solute always raises the freezing point of a solvent.
The freezing point depression only occurs in volatile solutions.
