To recover alcohol from a mixture with water, use distillation, which separates the components based on their boiling points. Heat the mixture so alcohol vaporizes first, then condense the vapors to collect the alcohol. This is a common technique in chemistry and beverage production.

To separate alcohol from a mixture with water, fractional distillation is the most effective method. This technique leverages the difference in boiling points between alcohol (ethanol) and water. Alcohol boils at a lower temperature (around 78°C) than water (100°C), allowing it to be vaporized and then condensed separately
