Question

7. 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?​

Answer 1

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 simple distillation.

The boiling point of kerosene = around 150–180 °C

The boiling point of petrol = 95 °C

Answer 2

We can separate a mixture containing 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 the simple distillation is given in the attachment.
