The Copper-Zinc Voltaic Cell is a great demonstration item for studying the conversion of chemical energy into electrical energy. The flow of an electric current occurs when two electrical conducting materials with different electrical potential, are connected together via a conducting wire. Electric current travels for the conductor with a higher potential to the conductor with a lower potential and this process of flow and current consumes energy. The electrical current will continue until a potential equilibrium is reached. Alessandro Volta discovered this around the end of the eighteenth century. He developed a cell that demonstrated how electro motive force (eml) is generated by chemical reactions. He also discovered that if a copper and zinc electrode are placed in a vessel containing dilute sulfuric acid that an electric current flowed through the wire. This type of electric cell was named after him. This kit provides you with the tools you need to recreate Volta’s cell. Included are copper and zinc electrodes and a plastic vessel with metal grips. This kit is excellent for classroom demonstrations and science projects.
