Electrolysis is a process that uses an electric current to drive a non-spontaneous chemical reaction. This technique is commonly used in various industrial processes, such as metal refining, production of chemicals, and water treatment. Electrolysis involves the use of electrodes placed in an electrolyte solution, where one electrode is connected to the positive terminal of a power supply (anode) and the other electrode is connected to the negative terminal (cathode). As the electric current passes through the electrolyte, chemical reactions occur at the electrodes, resulting in the formation of new substances. Although electrolysis is an energy-intensive process, it is vital for the production of materials and chemicals that cannot be easily obtained through other methods. Researchers are continuously working to improve the efficiency and cost-effectiveness of electrolysis for various applications.
