How will you separate a mixture containing kerosene and petrol (difference in their boiling points is more than 25°C), which are miscible with each other?

When the difference in the boiling points of two miscible liquids is 25°C or more, they can be separated by the process of ‘Simple Distillation’. In this case, the difference in the boiling points of kerosene and petrol is 25°C. Therefore, a mixture containing kerosene and petrol can be separated by the process of simple distillation. This can be done as follows: The mixture of kerosene and petrol is taken in a distillation flask fitted with a thermometer and a water condenser. The distillation flask is heated with a burner. Petrol will vaporise first as it has lower boiling point than kerosine. It will be condensed in the condenser and will be collected in the condenser outlet. Kerosene will be left behind in the distillation flask.
