Separation of a mixture of liquids by distillation Principle The separation of liquid mixtures can be achieved by a simple distillation. In this experiment a liquid mixture of water and ethanol is distilled by using a distillation column. Various fractions of the distillate are obtained with the help of a rotatable receiver. The composition (ethanol and water) of the individual fractions is determined by a measurement of the density. Learning objectives - Principle set-up of a destillation apparatus
- Seperation of liquid mixtures
- Composition of an ethanol/water-mixture
