H₂S Chemistry
Hydrogen sulfide is a molecule composed of one hydrogen atom and one sulfur atom. It is a colorless gas with a characteristic rotten egg smell. Hydrogen sulfide is produced naturally in the environment by the decomposition of organic matter, and it is also a component of crude oil and natural gas. It is used industrially in the production of sulfuric acid and other sulfur compounds. Hydrogen sulfide is toxic, and exposure to high levels can cause death.
Do You Know?
There is no one answer to this question. Each person’s understanding of what it means to “know” something will be different. Generally, though, when people say “I know,” they mean that they have a deep understanding or comprehension of the thing in question. They may know the facts about it, or they may know how to do it, or they may know how they feel about it. But in all cases, they know more than just the basics.
Hydrogen Sulfide Properties
Hydrogen sulfide is a colorless gas with a characteristic pungent odor. It is slightly soluble in water and is heavier than air. It is flammable and explosive in concentrations above 4% by volume. Hydrogen sulfide is used in the manufacture of sulfuric acid and other chemicals. It is also used as a fumigant and a corrosion inhibitor.

Hydrogen Sulfide Properties
Hydrogen sulfide is a colorless gas with a characteristic rotten egg smell. It is heavier than air and can cause suffocation. Hydrogen sulfide is a flammable gas and can form explosive mixtures with air. It is soluble in water and is corrosive to metals.
Hydrogen Sulfide Geometry
The geometry of hydrogen sulfide is trigonal pyramidal. The three hydrogen atoms are at the corners of the pyramid, and the sulfur atom is at the center.
Hydrogen Sulfide Preparation
To a round-bottom flask, add 3 mL of concentrated sulfuric acid and 1 mL of hydrogen sulfide. Swirl the flask to mix the contents.
Place the flask in a water bath and heat to 60 °C.
Add 1 mL of water and swirl the flask to mix the contents.
Remove the flask from the water bath and allow it to cool to room temperature.
The hydrogen sulfide solution is now ready to use.
Hydrogen Sulfide Uses
Hydrogen sulfide is used to make sulfur dioxide and sulfuric acid.
