Hydrogen sulfide MSDS.output.pdf
Description:
At high temperatures or in the presence of catalysts, sulfur dioxide reacts with hydrogen sulfide to form elemental sulfur and water. This reaction is exploited in the Claus process, an important industrial method to dispose of hydrogen sulfide.
Hydrogen sulfide is slightly soluble in water and acts as a weak acid, giving the hydrosulfide ion HS− (pKa = 6.9 in 0.01–0.1 mol/litre solutions at 18 °C). Hydrogen sulfide and its solutions are colorless. When exposed to air, it slowly oxidizes to form elemental sulfur, which is not soluble in water. The sulfide dianion S2− exists only in strongly alkaline aqueous solutions; it is exceptionally basic with a pKa > 14.

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
