Hydrogen Sulfide Oxidation by Chlorine
H2S + Cl2 → 2HCl + S
Visão geral
Chlorine oxidizes hydrogen sulfide to elemental sulfur while being reduced to hydrochloric acid. Sulfur is oxidized from -2 to 0. This reaction is used in removing hydrogen sulfide from natural gas (sweetening) and in treating hydrogen sulfide-containing wastewater.

Exemplo do cotidiano
The rotten egg smell of hydrogen sulfide from sewers can be eliminated by chlorination, which oxidizes H₂S to odorless elemental sulfur.
Importância industrial
A remoção de H₂S por oxidação com cloro é utilizada no adoçamento do gás natural, no tratamento de águas residuais e na indústria petrolífera. Os gases com H₂S são obrigatoriamente tratados antes de serem libertados para a atmosfera.
