To separate a mixture of kerosene and petrol, which are miscible liquids and have a boiling point difference of more than 25°C, we use the method of simple distillation.

Process of Simple Distillation:

  • The mixture is heated.
  • Petrol, which has a lower boiling point, boils and vaporizes first.
  • The vapors are passed through a condenser, where they cool and turn into liquid.
  • The condensed petrol is collected in a separate container.
  • Kerosene, with a higher boiling point, remains in the flask and can be collected later.

Hence petrol and kerosene are successfully separated based on their different boiling points.
