Question

I performed a lab experiment for Simple & Fractional Distillation.
For simple distillation I got 21.7% of methanol and 78.3% of water.
For fractional distillation I got 16.7% of methanol and 83.3% of water.

My question is: Did fractional distillation show better separation than simple distillation? Yes or no?
I confused in numbers.

Answer 1

Distillation is the separation technique used for the purification of liquid or mixture of liquids.Distillation include two processes, they are boiling and condensation.

The important difference between simple distillation and fractional distillation is separation of different components with boiling point gaps of atleast 50degrees is required but fractional distillation separates the components having closer boiling points.

Fractional distillation is used in crude oil refining and involve several steps and special apparatus for the purification.
