Hydrogen sulfide burns in oxygen with a blue flame to form sulfur dioxide (SO2) and water: 2 H2S + 3 O2 → 2 SO2 + 2 H2O. If an excess of oxygen is present, sulfur trioxide (SO3) is formed, which quickly hydrates to sulfuric acid: H2S + 2 O2 → H2SO4.

Hydrogen sulfide (also known as H 2 S, sewer gas, swamp gas, stink damp, and sour damp) is a colorless gas known for its pungent "rotten egg" odor at low concentrations. It is extremely flammable and highly toxic.

Hydrogen sulfide is produced naturally by decaying organic matter and is released from sewage sludge, liquid manure, sulfur hot springs, and natural gas. It is a byproduct of many industrial processes including petroleum refining, tanning, mining, wood pulp processing, rayon manufacturing, sugar beet processing, and hot asphalt paving.

Hydrogen sulfide, H 2 S, is a highly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent.

Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rot-ten egg” smell. Some common names for the gas include sewer gas, stink damp, swamp gas and manure gas. It occurs naturally in crude petroleum, natural gas, and hot springs.

Rapidly or completely vaporizes at atmospheric pressure and normal ambient temperature. Normally stable, even under fire conditions. A colorless gas having a strong odor of rotten eggs. Boiling point -60.2°C. Shipped as a liquid confined under …

Hydrogen sulphide is a colourless chalcogen hydride gas with the formula H 2 S. It is a highly corrosive, flammable and poisonous gas. Hydrogen sulphide is most commonly formed due to the microbial breakdown of organic matter in the absence of oxygen. This occurs mostly in swamps and sewers, and the process is known as anaerobic digestion.

Jul 28, 2023 · Hydrogen sulfide can be readily liquefied at a temperature of -61 °C and solidified at an even lower temperature of -85 °C. The H 2 S possesses the ability to undergo combustion, yet it does not act as a facilitator or enhancer of the combustion process.

Hydrogen sulfide is used in calibration gas mixtures for petrochemical industry, environmental emission monitoring, industrial hygiene monitors and trace impurity analyzers, especially to control hydrogen quality.
