Question

How will you separate two miscible liquids?

Answer 1

Distillation:

• Distillation is the separation of two miscible liquids. Distillation is used for liquids with a boiling point difference of $20$ to $30$ degrees Celsius.
• Throughout this technique, the liquid is heated in a distillation flask.
• The liquid with the lowest boiling point will boil first, and its vapours will be sent to the condenser, where they will be converted to liquid.
• The liquid with the greater boiling point is left behind in the distillation flask.

Fractional Distillation:

• Fractional distillation is a type of distillation that separates miscible liquids.
• The process employs repeated distillations and condensations, and the mixture is generally divided into component components.
• For liquids with a boiling point difference of less than $20°\mathrm{C}$, fractional distillation is utilised.
• It consists of a fractionating column that gathers liquids with different boiling points in distinct columns.

Thus, these two techniques can be used to separate two miscible liquids.
