Question

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

Answer 1

by the process of fractional disttilation..

Answer 2

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.
