What is a Sulphuretted hydrogen?
What is a Sulphuretted hydrogen?
a colourless poisonous soluble flammable gas with an odour of rotten eggs: used as a reagent in chemical analysis. Formula: H2S. Also called: sulphuretted hydrogen.
What is the meaning of H2S?
Hydrogen Sulfide (H2S) is a gas commonly found during the drilling and production of crude oil and natural gas, plus in wastewater treatment and utility facilities and sewers. Colorless, flammable, poisonous and corrosive, H2S gas is noticeable by its rotten egg smell.
What causes hydrogen sulfide gas?
Most hydrogen sulfide in the air comes from natural sources. It is produced when bacteria break down plant and animal material, often in stagnant waters with low oxygen content such as bogs and swamps. Volcanoes, hot springs and underwater thermal vents also release hydrogen sulfide.
Where hydrogen sulfide is found?
It is extremely flammable and highly toxic. Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes. Because it is heavier than air, hydrogen sulfide can collect in low-lying and enclosed spaces, such as manholes, sewers, and underground telephone vaults.
What is Sulphuric acid used for?
In various concentrations the acid is used in the manufacture of fertilizers, pigments, dyes, drugs, explosives, detergents, and inorganic salts and acids, as well as in petroleum refining and metallurgical processes.
Can H2 exist?
H2 is also called molecular hydrogen.It consists of two protons and two electrons. Consequently it is the most common form of Hydrogen because it is stable with a neutral charge. H2 is not a free radical.
Is H2 a gas?
H2, is an elemental gas with an atomic mass of 1.00794. This diatomic molecule is the lightest and most abundant element in the universe. It is also colorless, odorless, and highly flammable. Hydrogen; Hydrogen, H2, is the most abundant element in the universe.
What is another name for sulphuretted hydrogen?
Related to Sulphuretted hydrogen: choline. chemical compound, H2S, a colorless, extremely poisonous gas that has a very disagreeable odor, much like that of rotten eggs. It is slightly soluble in water and is soluble in carbon disulfide. Dissolved in water, it forms a very weak dibasic acid that is sometimes called hydrosulfuric acid.
What is the name of the compound H2S?
(also sulfuretted hydrogen), H2S, the simplest compound of sulfur with hydrogen. A colorless gas, hydrogen sulfide has the odor of rotten eggs when in an extremely rarefied state. Hydrogen sulfide was first studied in detail by K. Scheele in 1777.
What is hydhydrogen sulfide?
Hydrogen sulfide was first studied in detail by K. Scheele in 1777. It is a component of volcanic gases and certain mineral waters (at Kemeri, Piatigorsk, and Matsesta in the USSR). In the Black Sea, the compound is found at depths exceeding 150 m.
Is hydrogen sulfide flammable?
Hydrogen sulfide is flammable; in an excess of air it burns to form sulfur dioxide and water, but if not enough oxygen is present, it forms elemental sulfur and water. Hydrogen sulfide is found naturally in volcanic gases and in some mineral waters.
