Hydrogen disulfide is the inorganic compound with the formula H 2 S 2. This hydrogen chalcogenide is a pale yellow volatile liquid with a camphor-like odor. It decomposes readily to hydrogen sulfide (H 2 S) and elemental sulfur. [1]
The term/s acid gas and sour gas are often incorrectly treated as synonyms. Strictly speaking, a sour gas is any gas that specifically contains hydrogen sulfide in significant amounts; an acid gas is any gas that contains significant amounts of acidic gases such as carbon dioxide (CO 2) or hydrogen sulfide. Thus, carbon dioxide by itself is an ...
