Electrode Whewell at Faraday's request). The anode is now defined as the electrode at which electrons leave the cell and oxidation occurs (indicated by a minus symbol, "−"), and the cathode as the electrode at which electrons enter the cell and reduction occurs (indicated by a plus symbol, "+"). Each electrode may become either the anode or the cathode depending on the direction of current through the cell. A bipolar electrode is an electrode that functions as the anode of one cell and the cathode of another cell. A primary cell is a special type of electrochemical cell in which the
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
