Chemical Properties & Uses

Hydrogen sulfide is a colorless, flammable, poisonous gas with a rotten eggs odor. It burns in air with a pale blue flame. Hydrogen sulfide gas corrodes metals. Hydrogen sulfide is soluble in water, alcohol, ether, and glycerol. Water solutions of hydrogen sulfide are not stable, and because absorbed oxygen causes the formation of elemental sulfur, the solutions become turbid. The liquid form is stable at room temperature.

Hydrogen sulfide is emitted during the burning of sulfur-containing fuel oil and coal and wherever organic matter undergoes decomposition. It is also emitted from industrial paper plants using the kraft process. It may also be generated by the leather industry, which uses sodium sulfide to remove hair from hides prior to tanning. Large quantities are used in the production of heavy water for nuclear reactors. It is also used in the manufacture of chemicals, in metallurgy, and as an analytical reagent.

Hydrogen Sulfide (H2S) poses an extreme health hazard. Acute high-level exposure to hydrogen sulfide can cause immediate respiratory arrest. Hydrogen Sulfide (H2S) is highly toxic and proper safeguards, including gas monitoring, are deemed critical to industrial health and safety programs.
