1. Boiling Point: Ethyl alcohol has a lower boiling point (78.37 °C) than water (100 °C). This difference in boiling points allows for distillation. By heating the mixture, the alcohol will vaporize first. The vapor can then be collected and condensed back into liquid form, separating it from the water.
2. Density: Water is denser than ethyl alcohol. This property can be used in a separation funnel. The mixture is poured into the funnel, and the two liquids will separate into distinct layers. The denser water will settle at the bottom, while the less dense alcohol will float on top. The layers can then be drained separately.
