 to drive a chemical reaction. In our experiment, we use salt solution as one reactant, while the other reactant can be a metal or an alloy, like aluminium, tin or stainless steel. A circuit is created by attaching the negative electrode of a battery to a sheet of metal. The positive electrode is connected to the salt solution via a material like cotton which regulates it's supply on the metal surface. When electricity is introduced to this circuit, the salt solution breaks down into Na+ and Cl- ions. The positive sodium ions are attracted to the negative electrode while the chlorine ions move towards the positive electrode. The reaction of these ions with the respective electrodes caused the surface to disintegrate and thus get etched. Using different methods of exposing the electrolyte to the metal, we can create various etching patterns and images on the metal surface.
