SO2

General Information on SO₂

Sulfur dioxide (SO₂) is a colorless, mucous membrane-irritating, pungent-smelling and sour-tasting toxic gas. It is very soluble in water and forms sulfurous acid to a very small extent with water. It is formed, among other things, during the combustion of sulfur-containing fossil fuels such as coal or petroleum products. As a result, it contributes significantly to air pollution. Various processes exist for flue gas desulfurization. In addition, sulfur dioxide is found in the vicinity of active volcanoes.
