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?
A mixture of two miscible liquids having a difference in their boiling points
more than 25�C can be separated by the method of distillation. Thus, kerosene
and petrol can be separated by distillation.
In this method, the mixture of kerosene and petrol is taken in a distillation
flask with a thermometer fitted in it. We also need a beaker, a water condenser,
and a Bunsen burner. The apparatus is arranged as shown in the above figure.
Then, the mixture is heated slowly. The thermometer should be watched
simultaneously. Kerosene will vaporize and condense in the water condenser. The
condensed kerosene is collected from the condenser outlet, whereas petrol is
left behind in the distillation flask.
