Hypochlorite Oxidation of Hydrogen Peroxide

NaClO + H2O2 → NaCl + H2O + O2

Übersicht

Sodium hypochlorite oxidizes hydrogen peroxide to oxygen gas while being reduced to chloride. This vigorous reaction produces rapid oxygen evolution and is sometimes called the elephant toothpaste reaction when concentrated H₂O₂ is used with a catalyst. Both species undergo oxidation state changes.
