Question

what technique effectively separates mixtures of liquids that have different boiling points?
chromatography
filtration
magnetism
distillation

Explanation:

• Chromatography separates mixtures based on differential partitioning between a stationary and mobile phase, not boiling points.
• Filtration separates solids from liquids, not liquids by boiling point.
• Magnetism separates magnetic materials from non-magnetic ones, irrelevant to liquid boiling points.
• Distillation relies on heating a liquid mixture to vaporize the component with the lower boiling point, then condensing the vapor to separate it, which matches the requirement of separating liquids with different boiling points.

Answer:

distillation
