Hypochlorite Oxidation of Hydrogen Peroxide
NaClO + H2O2 → NaCl + H2O + O2
概述
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.
