Question

how will you separate a mixture containing kerosene and petrol (difference in their boiling point 25 C)which are miscible each other

Answer 1

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.

Answer 2

If two substance got mixed and they are miscible with less boiling point difference then we can't separate

But in this case we can separate Kerosene and petrol because ◆◆it has boiling point difference and it is adequate◆◆

Method we use to separate both individually is
