Process of Separating a Mixture of Two or More Liquids:
Fractional Distillation:
- Fractional distillation is the process of separating a mixture of two or more liquids with different boiling points.
- It involves collecting the vapors of the liquids at controlled temperatures.
- The mixture is heated in a fractional distillation apparatus, which consists of a fractionating column and a condenser.
- The fractionating column is packed with materials such as glass beads or metal wire to provide a large surface area for vaporization and condensation.
- The mixture is heated, and the component with the lower boiling point vaporizes first.
- The vapors rise through the fractionating column, where they condense on the packing material and then vaporize again.
- This process of vaporization and condensation occurs multiple times, allowing for the separation of different components based on their boiling points.
- The vapors of the different components are collected and condensed separately.
- The collected liquids can then be further purified or used for various purposes.
Other Options:
- Refining: Refining is a process used to purify substances, but it is not specifically used for separating a mixture of liquids based on their boiling points.
- Destructive Distillation: Destructive distillation is a process that involves heating a substance in the absence of air to produce useful products. It is not related to the separation of liquids based on their boiling points.
Therefore, the correct answer is fractional distillation.
