Sulfur oxide | Chemical Compound, Pollutant & Health Effects
sulfur oxide, any of several compounds of sulfur and oxygen, the most important of which are sulfur dioxide (SO 2) and sulfur trioxide (SO 3), both of which are manufactured in huge quantities in intermediate steps of sulfuric acid manufacture.
Sulfur Oxides - Center for Science Education
Sulfur oxides are a group of molecules made of sulfur and oxygen atoms, such as sulfur dioxide (SO 2) and sulfur trioxide (SO 3). Sulfur oxides are pollutants that contribute to the formation of acid rain, as well as particulate pollution.
9.8: Oxides and Oxyacids of Sulfur - Chemistry LibreTexts
Sulfur dioxide is formed as a pollutant during the combustion of sulfur containing fuels, in particular coal. While the emission of SO 2 itself leads to concerns it is its conversion to sulfuric acid in the form of acid rain that has been of concern for several decades.
Sulfur oxide - Wikipedia
Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO 2, SO 3, S 7 O 2, S 6 O 2, S 2 O 2, etc. Sulfur oxide (SOx) refers to one or more of the following: Lower sulfur oxides (S n O, S 7 O 2 and S 6 O 2)
Sources of Sulfur Oxides - Chemistry LibreTexts
Jun 21, 2021 · Electric power companies that burn coal are a major source of sulfur oxides. Other industrial plants contributed about 22 %. Smelting of metals such as copper, zinc, lead, and nickel can produce large amounts of sulfur dioxide.

Jan 31, 2024 · Sulfur dioxide (SO2) is one of a group of highly reactive gasses known as “oxides of sulfur," and are emitted into the air as result of fossil fuel combustion and other industrial processes.
Sulfur dioxide | Definition, Chemistry, Sources, Air Pollution,
Sep 19, 2024 · Sulfur dioxide has a pungent, irritating odor, familiar as the smell of a just-struck match. Occurring in nature in volcanic gases and in solution in the waters of some warm springs, sulfur dioxide usually is prepared industrially by the burning in air or oxygen of sulfur or such compounds of sulfur as iron pyrite or copper pyrite. Large ...
