  • H2S (van. nimetus väävelvesinik) mädamunalõhnaga mürgine värvuseta gaas; ... veeldub kergesti ..., vees lahustudes moodustab nõrga v.-happe. Looduses leidub vesiniksulfiidi peamiselt nafta- ja maagaasimaardlates, vulkaanilises gaasis ja mineraalvees.
  • a gas, H2S, with an odour of rotten eggs; r.d. 1.54 (liquid); m.p. -85.5°C; b.p. -60.7°C. It is soluble in water and ethanol and may be prepared by the action of mineral acids on metal sulphides, typically hydrochloric acid on iron(II)sulphide... In acid solution hydrogen sulphide is a mild reducing agent. Hydrogen sulphide has an important role in traditional qualitative chemical analysis, where it precipitates metals with insoluble sulphides... Hydrogen sulphide is exceedingly poisonous.
