I have also produce Electrolysis is the decomposition of a compound using electricity. When dissolved, the aluminium ions and oxide ions in the alumina can move. /**/ At the cathode: Here the aluminium ions receive electrons to become atoms again: At the anode: The oxide ions lose electrons to become oxygen molecules, O2: Uses of aluminium: 1. 1821 – Lithium was discovered by the English chemist William Thomas Brande, who obtained it by electrolysis of lithium oxide. 1834 – Michael Faraday published his two laws of electrolysis , provided a mathematical explanation for them, and introduced terminology such as electrode, electrolyte, anode, cathode, anion, and cation. The bauxite is purified to yield a white powder, aluminium oxide, from which aluminium can be extracted.
