Answer:
- 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.
