Sulfur oxides - Energy Education

Sulfur dioxide is colourless, but has a distinct smell and taste that can be detected if the gas has a high enough concentration. Sulfur oxides dissolve readily in water, and result in the atmospheric formation of sulfurous acid or sulfuric acid - a component of acid rain. The majority of sulfur oxides are produced when fuels that contain sulfur undergo combustion. As well, the roasting of metal sulfide ores is a major source.

How Is Sulphur Dioxide Formed? | Reference

Sulfur dioxide is a common byproduct of the incomplete combustion of fossil fuels. It is created when sulfur atoms present in the fuel are released into the atmosphere, joining with a pair of freed oxygen atoms. Sulfur dioxide also occurs as a byproduct of volcanic eruptions. Keep Learning.
