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 and the production of chemicals such as chlorine and hydrogen. The operation of an electrolytic cell is governed by principles of electrochemistry, which studies the relationship between electricity and chemical changes.
