Hydrogen Sulfide Oxidation by Chlorine

H₂S + Cl₂ → 2HCl + S

Tổng quan

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.
