An electrolytic cell is a device that uses electrical energy to drive a non-spontaneous chemical reaction. It consists of two electrodes: an anode and a cathode, immersed in an electrolyte solution. When a direct current is applied, positive ions move toward the cathode, where reduction occurs, while negative ions move toward the anode, where oxidation takes place. These cells are commonly used in processes like electroplating, where a metal layer is deposited onto a surface, and in the production of chemicals such as chlorine and sodium hydroxide. The principles of an electrolytic cell are essential in various industrial applications and scientific research.
