Practical experiment where learners produce ‘gold’ coins by electroplating a copper coin with zinc, includes follow-up worksheet

Use this microscale practical experiment to teach about the important industrial process of electroplating. It can be used to revisit some of the key concepts of electrolysis and the follow-up questions will help learners to consolidate their understanding of the processes. 

The resource supports the following learning objectives:

1 Understand that electroplating is an important industrial application of electrolysis.

2 Electroplate a coin.

3 Describe how to electroplate a metal.

4 Explain what happens at each electrode during electroplating.

The introduction and experiment relate to learning objectives 1 and 2. The questions relate to all learning objectives.

Suitable for learners following GCSE and equivalent courses.
