What produces H2S and water?
Sulfur-reducing bacteria, which use sulfur as an energy source, are the primary producers of large quantities of hydrogen sulfide. These bacteria chemically change natural sulfates in water to hydrogen sulfide.
How H2S is formed in water?
Hydrogen sulfide gas also occurs naturally in some groundwater, and is formed from decomposing underground deposits of sulfur-containing organic matter such as decaying plant material. It is found in deep or shallow wells and also can enter surface water through springs, although it quickly escapes to the atmosphere.
What is the product of H2S?
It is a colorless gas with an obvious identifying characteristic; it has a distinct rotten egg odor. Slightly denser than air, it can be incredibly explosive. When burning with oxygen, hydrogen sulfide burns blue, to form sulfur dioxide, and water.

How is h2s produced?
It is produced when bacteria break down plant and animal material, often in stagnant waters with low oxygen content such as bogs and swamps. Volcanoes, hot springs and underwater thermal vents also release hydrogen sulfide.
What is H2S in water?
Which process produces H2S?
The reduction of sulfur through the strains of bacteria will lead to the formation of hydrogen sulfide. Therefore, the correct option is (c) Anaerobic respiration.
How do you test for H2S in water?
The test is based on the readily observable formation of an iron sulfide precipitate on a paper strip (or in the water sample liquid) in a bottle or test tube, as a result of the reaction of H2S with iron.
How do you remove H2S from well water?
Aeration. Since hydrogen sulfide occurs as a gas in water, it can be physically removed by injecting air into the water and allowing the gas to escape. Aeration units may work by cascading, bubbling, or stripping the gas from the water.
Is H2S water soluble?
