Hydrogen sulfide is slightly soluble in water and acts as a weak acid (pK a = 6.9 in 0.01–0.1 mol/litre solutions at 18 °C), giving the hydrosulfide ion HS − (also written SH −). Hydrogen sulfide and its solutions are colorless. When exposed to air, it slowly oxidizes to form elemental sulfur, which is not soluble in water. See more Hydrogen sulfide is a chemical compound with the formula H 2S. It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul … See more Hydrogen sulfide is most commonly obtained by its separation from sour gas, which is natural gas with a high content of H 2S. It can also be produced by treating hydrogen with molten elemental sulfur at about 450 °C. Hydrocarbons can serve as a source of … See more Hydrogen sulfide is a highly toxic and flammable gas (flammable range: 4.3–46%). Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. … See more • Hydrogen chalcogenide – any binary compound of hydrogen with chalcogens, including hydrogen polychalcogenides • Hydrogen sulfide chemosynthesis • Sewer gas – complex mixture of toxic and nontoxic gases produced and collected in sewage systems by … See more Hydrogen sulfide is slightly denser than air. A mixture of H 2S and air can be explosive. In general, hydrogen sulfide acts as a reducing agent, although in the presence of a base, it can act as an acid by donating a proton and forming SH . Hydrogen sulfide … See more Production of sulfur, thioorganic compounds, and alkali metal sulfides The main use of hydrogen sulfide is as a precursor to elemental sulfur. Several organosulfur compounds are produced using hydrogen sulfide.
