You have a mixture of three liquids A, B and C. There is a large difference in the boiling points of A and rest of the two liquids i.e., B and C. Boiling point of liquids B and C are quite close. Liquid A boils at a higher temperature than B and C and boiling point of B is lower than C. How will you separate the components of the mixture. Draw a diagram showing set up of the apparatus for the process.
As per the information available in the question, liquid A boils at a higher temperature than B and C and boiling point of B is lower than C.
Therefore, the correct order of boiling point for all three compounds is:
A > C > B
As it has been provided in the question that there is a significant difference in the boiling points of A and B and C. So, it is possible to separate liquid A from the mixture through the process of simple distillation. The setup for simple distillation is: -
As the remaining two liquids B and C have close boiling points; thus the process of fractional distillation will be used for the separation of the two. The setup for fractional distillation is
