Question

Q.1 Two liquids 'A' and 'B' are miscible with each other at room temperature. Which separation
technique will you apply to separate the mixture of 'A' and 'B' if the difference in their boiling point
is 27 deg C?
​

Answer 1

Answer: use of fractional distillation because of their differences in boiling points

Explanation:

Miscible liquids are those liquids which when mixed together form one liquid without a layer.

So when liquid A and B are mixed, due to their difference in boiling points fractional distillation which takes advantage of the 27 degree boiling difference is used to separate them

Answer 2

To separate a mixture containing kerosene and petrol (difference in their boiling points is more than 25°C), Fractional distillation method is used.
