Final answer:
The freezing point of a solution is lower than its pure solvent, while the boiling point of a solution is higher.
Step-by-step explanation:
The freezing point of a solution is lower than that of its pure solvent, and the boiling point of a solution is higher than that of its pure solvent.
When a solute is dissolved in a solvent, the freezing point of the solution is lowered. This is because the solute particles disrupt the crystal lattice structure of the solvent, making it more difficult for the solvent to freeze.
On the other hand, the boiling point of a solution is higher than the boiling point of the pure solvent. This is because the solute particles increase the vapor pressure of the solution, requiring a higher temperature for the solution to boil.
