Experiment

Electrolysis of brine

In association with Nuffield Foundation

Use this colourful practical to introduce students to the electrolysis of brine, or sodium chloride solution. Includes kit list and safety instructions.

Experiment

The equilibrium between two coloured cobalt species

In association with Nuffield Foundation

In this demonstration the equilibrium between two different coloured cobalt species is disturbed. Le Chatelier’s principle is used to predict a colour change.
