Uses: Hydrogen Sulfide - H2S - is used in metallurgy for the preparation of metallic sulfides. It is also used in the preparation of phosphors, oil additives, and as an analytical reagent in chemical analysis. It is in metals separation, removal of metallic impurities and for reaction with numerous functional organic compounds. ( Reference to: Sulfur Compounds)
