Electrolysis is a key electrochemical process used to decompose ionic compounds into their elements. It involves applying a direct current to an electrolyte, causing cations to move to the cathode and anions to the anode, resulting in reduction and oxidation reactions. This process is crucial in industries for metal extraction, substance purification, and electroplating. Factors like ion concentration and electrode material affect the outcomes, with applications ranging from metal purification to hydrogen production.
