You have a mixture of three liquids A, B, C. there is a large difference in the boiling point of A and the rest two liquids. Boiling points of liquids B and C are quite close. Liquid A boils at higher temperature than B and C and boiling point of B is lower than C. How will you separate the components of the mixture?

1.	You have a mixture of three liquids A, B, C. there is a large difference in the boiling point of A and the rest two liquids. Boiling points of liquids B and C are quite close. Liquid A boils at higher temperature than B and C and boiling point of B is lower than C. How will you separate the components of the mixture?
Answer» Since the boiling point of liquid A is much higher than those of liquids B and C, therefore separate liquid A by simple distillation. Since boiling points of liquids B and C are quite close but much lower than liquid A therefore mixture of B and C will distil together leaving behind A. On further heating, A will distil over. Now place the mixture of liquids B and C in a flask fitted with fractionating column. Since the boiling point of liquid B is lower than that of C, on fractional distillation first liquid B will distil over and then liquid C.
