Dihydrogen monosulfide H2S 99.9% Used In Analytical Chemistry
Description:
Hydrogen sulfide is a highly toxic and flammable gas. Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces.
Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs. These effects are believed to be due to the fact that hydrogen sulfide combines with alkali present in moist surface tissues to form sodium sulfide, a caustic. These symptoms usually go away in a few weeks.

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
