Hydrogen Sulfide Oxidation by Chlorine

H2S + Cl2 → 2HCl + S

अवलोकन

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.
