Distillation: simple distillation
I can identify equipment needed to carry out simple distillation and explain how the process works.
Distillation: simple distillation
I can identify equipment needed to carry out simple distillation and explain how the process works.
Lesson details
Key learning points
- Distillation separates a soluble substance from its solvent based on differences in boiling points.
- Distillation requires multiple pieces of apparatus which work in conjunction with each other.
- The processes of boiling and condensing are involved in the process of distillation.
- Simple distillation is used primarily to separate mixtures of only two components.
Common misconception
Students struggle to understand gas state; thinking solids, liquids and gases as 'types' of matter.
Refer to/use particle models to help clarify different states of matter and use these to describe why separation techniques work.
Keywords
Boiling - Boiling occurs when a substance in the liquid state is heated and changes to the gas state with gas bubbles formed.
Condensation - Condensation is the process by which a substance in the gas state is cooled and changes to a liquid state.
Distillation - Distillation is a separation technique that uses boiling and condensation to remove and isolate a liquid component of a mixture.
Condenser - A condenser is a piece of apparatus composed of a tube surrounded by a cold layer, usually cold water.
Distillate - A distillate is the condensed component that has been isolated during distillation.
