Question

Identify the CORRECT statement.

Options

• Vapour pressure of solution is higher than that of pure solvent.

• Boiling point of solvent is lower than that of solution.

• Osmotic pressure of solution is lower than that of solvent.

• Osmosis is a colligative property.

Answer 1

Boiling point of solvent is lower than that of solution.

Explanation:

Because the solution with the lower vapour pressure must be heated to a higher temperature in order for the vapour pressure to match the external pressure, the boiling point of the solution will be higher than the boiling point of the pure solvent.
