Distillation
This lesson covers:
- The process of simple distillation
- The process of fractional distillation
The steps of simple distillation:
evaporates / gas / Bunsen / condenses
- A solution is heated, usually using a burner.
- The liquid in the mixture into a gas.
- The gas is cooled by a water jacket, and into a liquid, which then flows into the beaker.

Fractional distillation can separate a mixture of several liquids that each have different:
Boiling points
Colours
Melting points
|
Which of the following is the correct order of steps required for fractional distillation?
Condenser ➔ beaker ➔ fractionating column ➔ boiling flask
Boiling flask ➔ condenser ➔ beaker ➔ fractionating column
Boiling flask ➔ fractionating column ➔ condenser ➔ beaker
