WebElectrolysis of water, also known as water splitting, is the process of using electricity to decompose water into oxygen (O 2) and hydrogen (H 2) gas by electrolysis.Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, for use in welding and other applications.. Water electrolysis requires … Webelektroliza wodnego roztworu chlorku sodu (NaCl): Na anodzie wydziela się chlor: Cl − → ½Cl 2 + e − Na katodzie zobojętnieniu ulegają jony wodorowe pochodzące z wody: H 3 O + + e − → H 2 O + ½H 2. Wodorotlenek sodu powstaje także m.in. w reakcji wody z sodem lub niektórymi jego reaktywnymi związkami (np.

WebEfficiency. High temperature electrolysis is more efficient economically than traditional room-temperature electrolysis because some of the energy is supplied as heat, which is cheaper than electricity, and also because the electrolysis reaction is more efficient at higher temperatures. In fact, at 2500 °C, electrical input is unnecessary because water breaks … WebМыслитель.
