Question

Which statement is CORRECT for the boiling point of solvent containing a dissolved non-volatile solute?

Options

• Boiling point of the liquid gets lowered.

• Boiling point of the liquid gets elevated.

• There is no effect of the added solute on the boiling point.

• The change depends upon the nature of the solute.

Answer 1

Boiling point of the liquid gets elevated.

Explanation:

When a non-volatile solute is dissolved in a liquid solvent, the boiling point of the resulting solution is raised due to a reduction in the solution's vapour pressure. Boiling point elevation is a colligative feature that is reliant only on the amount of solute particles and is unaffected by the solute's type.
