Introduction

Distillation is a commonly used method in chemistry for separating and purifying different components of a mixture. The process involves heating the mixture to vaporize one or more of its components, then cooling and condensing the vapor back into a liquid.

The principle of distillation is based on the fact that different substances have different boiling points, and therefore can be separated by heating the mixture to a temperature at which one of the components vaporizes while the others remain in a liquid state. The vaporized component is then collected and condensed back into a liquid, while the remaining components are left behind.
