ABSTRACT A Fruit battery is a device used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallic objects‚ for example a galvanized nail and a copper coin‚ into an ion bridge (for example a lemon‚ a potato or paper soaked in salt water or acid). The copper coin serves as the positive electrode or cathode and the galvanized nail as the electron-producing negative electrode or anode. These two objects work as electrodes‚ causing anelectrochemical
