Use this demonstration to show how pure water can be recovered from copper sulfate solution using a condenser. Includes kit list and safety instructions.

When copper sulfate solution is boiled, pure water vapour is produced. In this experiment, students observe how this may be captured using a water-cooled condenser, producing liquid water with a boiling point of 100°C.
