Question

Describe the technique of separation of a mixture by distillation?

Answer 1

Distillation:

• Distillation is the process of the separation of a liquid from its solution with a solid constituent by heating the liquid to its vapour form and then cooling the vapour to get back the pure liquid.
• This method is used to recover both the dissolved solids and the liquid from their mixture.

The technique of separation:

• When the homogeneous mixture of a solid and a liquid is heated in a distillation flask, the liquids form vapours.
• These vapours passed through a condenser in which they get cooled and condense to form the pure liquid.
• This pure liquid is called the distillate.
• The distillate is collected in a separate flask.
• The solid is left behind in the distillation flask.
• For example, pure water or distilled water can be obtained from tap water by the process of distillation.
