Question

substance lewis diagram molar mass (g/mol) density (g/ml) boiling point (k) methanol h o ch₃ 32 0.79 338 water h o h 18 1.0 373 when methanol and water are mixed together, they form a homogeneous mixture. based on the information in the table above, which of the following would be the best procedure for separating a mixture of methanol and water? a filtration b distillation c paper chromatography d column chromatography

Explanation:

Filtration is for separating solids from liquids. Paper and column chromatography are used for separating mixtures based on different affinities for a stationary and mobile phase. Since methanol and water are a homogeneous liquid - liquid mixture with different boiling points (338 K for methanol and 373 K for water), distillation is the best method as it separates components of a liquid - liquid mixture based on differences in boiling points.

Answer:

B. Distillation
