This lesson covers the AQA Required Practical for investigating the electrolysis of aqueous solutions using inert electrodes, as specified in AQA GCSE Chemistry (Required Practical 2, specification 4.4.3). You must be able to describe the apparatus, carry out the practical, identify the products at each electrode, and explain the results using knowledge of ions and redox chemistry. This practical is commonly examined and connects theory directly to laboratory skills.
To investigate what happens during the electrolysis of different aqueous solutions using inert (unreactive) electrodes, and to identify the products formed at each electrode.
