Hydrogen Sulfide Reaction With Water
On the Reaction of Hydrogen Sulfide and Water
Hydrogen sulfide is a genus of gas. When it encounters water, it changes. Hydrogen sulfide dissolves in water and forms a liquid of hydrosulfuric acid.
The reaction between the two, hydrogen sulfide ($H_2S $) enters water, and a few hydrogen sulfide molecules dissociate. First, $H_2S H ^ ++ HS ^ - $, this step dissociates, hydrogen protons ($H ^ + $) and hydrogen sulfide ions ($HS ^ - $). Although the dissociation is weak, the solution is weakly acidic.
Furthermore, hydrogen sulfide ions ($HS ^ - $) can be re-dissociated, $HS ^ - H ^ ++ S ^ {2 -} $, and the dissociation benefit of this step is weaker than before. However, two steps of dissociation cause changes in the composition of ions in water, the number of hydrogen ions ($H ^ + $) increases, and the pH value of the solution decreases.
This reaction is involved in the natural environment and the chemical industry. In nature, near volcanic craters and hot springs, hydrogen sulfide or released in gas enters water to form this reaction. In chemical production, the process of hydrogen sulfide is involved, and this reaction also needs to be considered, which is related to the purity of the product and the protection of equipment.
The reaction between hydrogen sulfide and water, although its shape is small, it is significant in many aspects and cannot be ignored.
