Question

How can we separate a mixture of petrol and kerosene oil?

Answer 1

We can separate a mixturecontaining kerosene and petrol by simple distillation because kerosene and petrol do not decompose on heating and their boiling points are sufficiently apart. The apparatus used for simple distillation is given below. Take the given mixture in a distillation flask.

Answer 2

kerosene and petrol are miscible liquids also the difference between their boiling point is more than 25 ºC so they can be separated by the method of distillation. Follow the steps given below(i) Take a mixture in the distillation flask fit it with the thermometer.(ii) Arrange the apparatus as shown in the given figure.(iii) Heat the mixture slowly keeping a close watch on thermometer.(iv) Since the petrol has lower boiling point starts vaporises and condenses in the condenser which is finally collected in the beaker.
