What method is BEST suited to separate a mixture of two miscible liquids with different boiling points (e.g. water and ethanol)?
ASedimentation
BDistillation (or fractional distillation)
CFiltration
DEvaporation
Answer & Solution
Correct answer: B. Distillation (or fractional distillation)
Distillation works by heating the mixture — the more volatile liquid (lower boiling point) vaporises first, is condensed and collected, separating it from the less volatile one. Filtration is for solid-liquid mixtures; evaporation only recovers the solid; sedimentation lets heavier solids settle.
