These diagnostic questions and response activities (contained in the zip file) support students in being able to:
- Describe the process of electrolysis in terms of chemical reactions occurring at the electrodes.
- Identify the cathode (or anode) in a diagram of the electrolysis of a solution of an ionic compound.
- Explain the conduction of electricity by a solution of an ionic compound.
- Explain the formation of a metal at the cathode in terms of the gain of electrons by ions to firm atoms.
- Explain the observed formation of a gas at the cathode.
The resources include details of common misconceptions and a summary of the research upon which the resources are based.
