hydrogen sulfide
(redirected from Hydrosulphuric acid)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
hydrogen /hy·dro·gen/ (H) (hi´dro-jen) chemical element, at. no. 1; it exists as the mass 1 isotope (protium, light or ordinary h.), mass 2 isotope (deuterium, heavy h.), and mass 3 isotope (tritium) .
hydrogen cyanide  an extremely poisonous liquid or gas, HCN, used as a rodenticide and insecticide.
hydrogen peroxide  a strongly disinfectant cleansing and bleaching liquid, H2O2, used in dilute solution in water.
hydrogen sulfide  an ill-smelling, colorless, poisonous gas, H2S.

hydrogen sulfide
n.
A colorless, flammable poisonous gas that has a characteristic rotten-egg odor, is formed in the decomposition of organic matter containing sulfur, and is used as an antiseptic, a bleach, and a reagent.

hydrogen (H) [hi´dro-jen]
a chemical element, atomic number 1, atomic weight 1.00797. (See Appendix 6.) It exists as the mass 1 isotope (protium, or light or ordinary hydrogen), mass 2 isotope (deuterium, heavy hydrogen), and mass 3 isotope (tritium).
hydrogen cyanide an extremely poisonous colorless liquid or gas, HCN, a decomposition product of various naturally occurring glycosides and a common cause of cyanide poisoning. Inhalation of the gas can cause death within a minute. Called also hydrocyanic acid.
heavy hydrogen deuterium.
hydrogen ion concentration the degree of concentration of hydrogen ions (the acid element) in a solution. Its symbol is pH, and it expresses the degree to which a solution is acidic or alkaline. The pH range extends from 0 to 14, pH 7 being neutral, a pH of less than 7 indicating acidity, and one above 7 indicating alkalinity. See also acid-base balance.
hydrogen peroxide H2O2, an antiseptic with a mildly antibacterial action. A 3 per cent solution foams on touching skin or mucous membrane and appears to have a mechanical cleansing action.
hydrogen sulfide H2S, a poisonous gas with an offensive smell, released from decaying organic material, natural gas, petroleum, and sulfur deposits, and sometimes used as a chemical reagent.

hydrogen
a chemical element, atomic number 1, atomic weight 1.00797, symbol H. See Table 6. It exists as the mass 1 isotope (protium, or light or ordinary hydrogen), mass 2 isotope (deuterium, heavy hydrogen), and mass 3 isotope (tritium).

hydrogen bonding
weak electrostatic attraction between one electronegative atom and the hydrogen atom covalently linked to a second electronegative atom.
hydrogen breath test
detects hydrogen production as a product of bacterial fermentation of carbohydrates, an indicator of inflammatory bowel disease or carbohydrate malabsorption.
hydrogen cyanide
hydrocyanic acid.
heavy hydrogen
hydrogen having double the mass of ordinary hydrogen; deuterium.
hydrogen ion balance
hydrogen ion concentration
the degree of concentration of hydrogen ions (the acid element) in a solution. Its symbol is pH, and expresses the degree to which a solution is acidic or alkaline. The pH range extends from 0 to 14, pH 7 being neutral. A pH of less than 7 indicates acidity, above 7 indicates alkalinity. See also acid-base balance and ph.
hydrogen peroxide
H2O2, used in solution as an antibacterial agent. A 3% solution foams on touching skin or mucous membrane and appears to have a mechanical cleansing action.
hydrogen peroxide-based teat dips
hydrogen sulfide
an ill-smelling, colorless, poisonous gas, H2S; much used as a chemical reagent. Hydrogen sulfide is often present in gases from oil wells and from manure vats under slatted floor barns. Poisoning of cattle causes diarrhea, dehydration, dyspnea and death in convulsions. The feces are black and the breath smells of hydrogen sulfide. Called also hydrosulfuric acid. See also manure pit gas poisoning.
hydrogen swell
defective canned meat can. Can is distended due to production of hydrogen as a result of corrosion of the can surface.

sulfide
any binary compound of sulfur; a compound of sulfur with another element or base.

hydrogen sulfide
see hydrogen sulfide.

hy·dro·gen sul·fide
H2S; a colorless, flammable, toxic gas with a familiar "rotten egg" odor, formed in the decomposition of organic matter containing sulfur; used as a reagent, and in the manufacture of chemicals.
Synonym(s): sulfureted hydrogen

hy·dro·gen sul·fide (hīdrō-jen sŭlfīd)
A fetid poisonous gas that smells like rotten eggs.

hy·dro·gen sul·fide (hīdrō-jen sŭlfīd)
Colorless, flammable, toxic gas with familiar "rotten egg" odor.
