Concept Distillation separates two or more liquid components in a mixture using the principle of relative volatility or boiling points. The greater the difference in relative volatility the greater the nonlinearity and the easier it is to separate the mixture using distillation. Objectives The objective of this experiment is to apply the process of distillation to a mixture of ethanol and water to obtain a new mixture with an increased concentration of ethanol. In addition, the results of the experiment will be used to approximate the equilibrium relationship between ethanol and water. Specifically
