Electrolysis is the process by which ionic substances are decomposed into simpler substances when an electric current is passed through them.
In the medieval times, aluminium was almost as precious as silver. Its extraction was not known and pure aluminium was extremely hard to come by. The application of electrolysis turned aluminium from a precious metal to one of the most largely used metals by humans. Aluminium is extracted from its ore by the process of electrolytic decomposition and deposition.
