Question

Explain the following method of separation with an example each:

Fractional distillation

Answer 1

Fractional distillation:

• It is the type of separation technique that is used to separate a mixture of liquid-based upon their boiling point.
• In this method distillation and condensation are repeated various times.
• This repeated process results in the separation of liquid.
• The substance with a lower melting point will separate first in another beaker.
• For example, A common example of fractional distillation in industries is the separation of various components of crude oil.
• Crude oil normally contains substances such as paraffin wax, gasoline, diesel, naphtha, lubricating oil, and kerosene.
• The distillation process helps in separating these components effectively.
