Question

a mixture contains two liquids a and b which differ in their be PT by 20k. suggest a suitable process to separate them . draw a neat diagram to explain the process

Answer 1

Distillation is a process where a mixture made of two or more liquids (called "components") with different boiling points can be separated from each other. The mixture is heated until one of the components boils (turns to a vapor).

Answer 2

The suitable process of separation of two liquids a and b is fractional distillation.

• Since the two liquids, a and b differ in their PT by 20K that means they are immiscible with each other that is when they are mixed together they do not get mixed to form one single liquid.
• Fractional distillation is the only separation process that can be used to separate these two liquids a and b.
• Fractional distillation is the process of separating the parts of a liquid mixture with the help of heating.
• When the mixture is heated the liquids get heated up and causing each part to get to become gas which is then cooled down as they move up the glass tube and are collected as liquids.
• The glass tube along which the gaseous form of the liquid rises where they get cooled down for continuous flow of cold water along the wall is called a fractional column.
