Question

Introduction to Hydrogen Sulfide.

Answer 1

Hint :First we know that Hydrogen sulfide consists of a single sulfur atom bonded to two hydrogen atoms. Its molecular formula is $ {H_2}S $ .It is highly poisonous, flammable gas with a characteristic odour of rotten eggs.

Complete Step By Step Answer:
Hydrogen sulfide also known as sewer gas, swamp gas, stink damp, and sour damp. It is extremely flammable and highly toxic. It is colourless and it is typically found in a gaseous state with a boiling point $ - {60.4^0} $ C. It is heavier and denser than air with a density of $ 1.1363 $ relative to air. It is highly explosive and reactive in the presence of strong nitric acid. It spontaneously catches fire at a temperature which is approximately $ 518F $ . When Hydrogen Sulfide is burned, it produces sulfur dioxide.
Hydrogen sulfide occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs. It is produced by bacterial decomposition of organic matter in the absence of oxygen. It is also produced by human and animal wastes. Bacteria found in your mouth and gastrointestinal tract produce hydrogen sulfide from bacteria decomposing materials that contain vegetable or animal proteins.

Note :
Hydrogen sulfide is used in production of sulfur, thiol organic compounds, and alkali metal sulfides. The main use of hydrogen sulfide is that several organosulfur compounds are produced using hydrogen sulfide. When dissolved in water it will form hydro sulfuric acid. It is corrosive to metals as it forms metal sulfides.
