Explanation
Electrolysis uses electrical energy to break down compounds into elements. Water electrolysis produces hydrogen and oxygen gases. Electrolysis is used to extract metals from ores and purify metals. In electroplating, electrolysis deposits a metal coating on an object. The products of electrolysis depend on the compound and electrodes used. Electrolysis is essential in many industrial processes.
Example
During water electrolysis with electrical current, water breaks down into hydrogen gas at the cathode and oxygen gas at the anode.
