Hydrogen sulfide
From BioMineWiki
Formula: H2S
A colourless, toxic, flammable gas with a characteristic smell of rotten eggs. It is found naturally in volcanic gases and is often formed during decay of animal matter. Hydrogen sulfide is slightly soluble in water forming a very weak dibasic acid that is sometimes called hydrosulfuric acid.
It is used as an antiseptic, a bleach and as a chemical reagent.
Production
Hydrogen sulfide may be produced by
- reacting hydrogen gas with molten sulfur or sulfur vapours
- treating a metal sulfide with an acid.
- THIOTEQ bioreactor
