Galvanic cell bridge zinc ions leave and anions enter the zinc half-cell. In the copper half-cell, the copper ions plate onto the copper electrode (reduction), taking up electrons that leave the external conductor. Since the Cu ions (cations) plate onto the copper electrode, the latter is called the cathode. Correspondingly the zinc electrode is the anode. The electrochemical reaction is: In addition, electrons flow through the external conductor, which is the primary application of the galvanic cell. As discussed under #Cell voltage, the emf of the cell is the difference of the half-cell potentials, a measure of the relative ease of dissolution
Electrolytic Zinc Electrolytic Zinc Electrolytic Zinc or the Electrolyic Zinc Company of Australasia (frequently abbreviated to "EZ" ) was the company that operated a Zinc refinery on the banks of the Derwent River in Risdon in Hobart in Tasmania between 1916 and 1984. The refinery was often given names such as the "Risdon works", the "Zinc works","reduction works" The current usage and place name located at the Risdon works is identified as Lutana. The operations of the Risdon works were tied in with the mining of zinc in Rosebery on the West Coast of Tasmania. The company started operation in 1916 at
