Power Supply Hydrolysis of Water Cathode Anode Acid Base AC/DC Converter Cathode Anode AC in DC out e- e- e- e- e- Hydrolysis of Water e- H2 O2 H2 O2 Acid Base H2 H2 H2 O2 e- e- e- e- e- H2 H2 O2 H2 H2 O2 e- e- H2 H2 O2 H2 2H20 O2(g) +4H+(aq) + 4e- Water is oxidized at the Cathode (+) end. 4H2O + 4e- 2H2(g) + 4OH-(aq) Water is reduced at the Anode (-) end. Net Cell Reaction 2H2O(L) 2H2(g) + O2(g) Decomposition of water is a redox reaction. In the decomposition reaction, the volume of H2 produced is twice that of O2.
