General information on H2S / Schwefelwasserstoff

Hydrogen sulfide (H2S) (also dihydrogen sulfide,) is a malodorous, colorless, highly toxic gas. It is corrosive, flammable, highly combustible, and slightly heavier than air. It is slightly soluble in water and slightly more soluble in ethanol. H2S is a very weak acid whose salts are the sulfides and hydrogen sulfides. Even in very low concentrations, hydrogen sulfide can be recognized by its typical rotten egg smell. It is formed, among other things, during the decomposition of sulfur-containing amino acids in biogas plants with concentrations of up to 10,000 ppm.
