Electrolysis is the passing of a direct electric current through an electrolyte producing chemical reactions at the electrodes and decomposition of the materials. The main components required to achieve electrolysis are an electrolyte, electrodes, and an external power source. A partition (e.g. an ion-exchange membrane or a salt bridge) is optional to keep the products from diffusing to the vicinity of the opposite electrode. WebDecomposition potential of water This determines the value of the reversible decomposition potential of water if hydrogen escapes into the atmosphere at a pressure of pHa and oxygen at a pressure of pQi.
