Electrolysis: Discovery, Process, and Industrial Applications

The video explains the process of electrolysis, starting with its historical context and Davy's pioneering experiments. It details how electrolysis splits compounds like potassium hydroxide into elements, using electric currents and electrodes. The video also covers the ionic mechanisms involved and highlights the industrial applications of electrolysis, particularly in extracting metals like aluminium.

Explain how electrolysis can only work with metal compounds that are molten or dissolved.

What happens to the negatively charged hydroxide ions at the anode during electrolysis?
