Distillation
This practical lesson covers:
- How to separate a mixture using distillation
Investigating the process of distillation
Aim
To separate a mixture into its constituent parts through the process of distillation.
Background information
Distillation is a separation technique that separates mixtures with different boiling points. In this practical, you will be using distillation to separate a mixture into its individual components and record the boiling point of each.
What is the purpose of distillation?
to separate a mixture into its constituent parts based on their boiling points
to change a solid into a gas
to combine different substances into a mixture
|
What equipment is needed for distillation?
microscope, petri dish, sample to be observed
test tubes, pipettes, sample to be tested
distillation apparatus, Bunsen burner, thermometer, sample to be distilled, beakers
|
What happens during the process of distillation?
the mixture is stirred, the components mix together and form a new substance
the mixture is cooled, the components solidify and fall to the bottom of the flask
the mixture is heated, the volatile components vaporise and travel up the column, then condense into a liquid and collect in the receiver
