Question

question 1. equal amounts of ethanol and water are mixed at room temperature (25°c) and at 101.3 kpa. which process is used to separate ethanol from the mixture?
distillation.
chromatography.
filtration.
magnetism.

Explanation:

Ethanol and water form a homogeneous mixture with different boiling - points. Distillation is a separation technique based on differences in boiling points. Chromatography separates based on different affinities for a stationary and mobile phase. Filtration is for separating solids from liquids. Magnetism is for separating magnetic substances. Since ethanol and water have different boiling points, distillation is used.

Answer:

Distillation.
