Half reaction of water

WebJan 7, 2016 · Reduction half reaction: O X 2 + 4 H X + + 4 e X − 2 H X 2 O. After balancing and summing, I get: 2 S O X 2 + 2 H X 2 O + O X 2 + 4 H X + 2 S O X 3 + 2 H X 2 O + 4 H X +. By cancelling H X 2 O and H X + we obtain the desired redox equation. The used half equations necessitate the presence of water and acidic medium at first, but in reality we ... WebJul 19, 2024 · Corrosion of metals is a serious economic problem. Corrosion occurs as a result of spontaneous electrochemical reaction as metal undergoes oxidation. For example, the rusting of iron begins with the oxidation of solid iron: Fe ( s) → Fe 2 + ( aq) + 2 e −. The corresponding reduction reaction involves water: H 2 O ( l) + 1 2 O 2 ( g) + 2 e ...
