Question

A pure solvent has a boiling point ____ the boiling point of a solution.

A. Equal to
B. Lower than
C. Higher than

Answer 1

Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water.

So the correct answer is C.
