Sulfureted Hydrogen H2S 3N 99.9% Sulfane Sulfur hydride Used As Fuel
Description:
A standard lab preparation is to treat ferrous sulfide with a strong acid in a Kipp generator:
FeS + 2 HCl → FeCl2 + H2S
For use in qualitative inorganic analysis, thioacetamide is used to generate H2S:
CH3C(S)NH2 + H2O → CH3C(O)NH2 + H2S
Many nonmetal sulfides, e.g. aluminium sulfide, phosphorus pentasulfide, silicon disulfide liberate hydrogen sulfide upon exposure to water:
6 H2O + Al2S3 → 3 H2S + 2 Al(OH)3
This gas is also produced by heating sulfur with solid organic compounds and by reducing sulfurated organic compounds with hydrogen.

Applications:
Production of thioorganic compounds
|
Several organosulfur compounds are produced using hydrogen sulfide. These include methanethiol, ethanethiol, and thioglycolic acid
|
Analytical chemistry
|
For well over a century, hydrogen sulfide was important in analytical chemistry, in the qualitative inorganic analysis of metal ions
|
Precursor to metal sulfides
|
As indicated above, many metal ions react with hydrogen sulfide to give the corresponding metal sulfides
|
Miscellaneous applications
|
Miscellaneous applications: Hydrogen sulfide is used to separate deuterium oxide, or heavy water, from normal water via the Girdler sulfide process
