Hypochlorite Oxidation of Hydrogen Peroxide

NaClO + H2O2 → NaCl + H2O + O2

Visão geral

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.

Exemplo do cotidiano

Mixing bleach with hydrogen peroxide in cleaning produces a vigorous fizzing reaction, though this is not recommended due to potential hazards.

Importância industrial

Compreender a interação entre estes oxidantes comuns é importante para a segurança química. Misturar lixívia com peróxido de hidrogénio pode gerar oxigénio rapidamente, o que pode ser perigoso em espaços fechados. Esta reação é utilizada para geração controlada de oxigénio.
