The video explains the basic components of electrolysis, which include two electrodes and an electrolyte that can be an ionic solution or a fused ionic compound. It further describes the process of extracting aluminium by electrolysing molten aluminium oxide in a cell with carbon electrodes, resulting in the production of aluminium and carbon dioxide.
