Distillation is the process of separating the components of mixture by using techniques of boiling and condensation It is mainly used to separate liquid mixtures It works on the principle of separation basing on the differences in their volatility Volatility is nothing but the capacity to vaporize. Boiling and condensation are quite reverse processes. Boiling is the process in which liquid phase of matter is converted into vapour on heating whereas condensation is conversion of vapour state into liquid on cooling. The apparatus of distillation include following parts: 1. Round bottomed flask 2. Thermometer 3. Condenser 4. Impure liquid mixture 5. Spirit lamp 6. Beaker to collected liquid seperated 7. Retort stand Round bottomed flask is the apparatus to heat the impure liquid mixture with spirit lamp. The components of the mixture will have different boiling points so that the component with less boiling point will vaporize first and get separated by passing through the condenser and collected as liquid in the beaker
