Sulfur dioxide (SO2) is a chemical compound composed of one sulfur (S) atom and two oxygen (O) atoms bonded together. In its molecular structure, one sulfur atom shares electrons with two oxygen atoms, forming covalent bonds. This arrangement results in the formation of a stable molecule of sulfur dioxide.
Sulfur dioxide is a colorless gas with a sharp, pungent odor. It is produced through various natural and anthropogenic processes, including volcanic eruptions, combustion of fossil fuels, and industrial activities such as smelting and refining of metals. Sulfur dioxide is a key component of air pollution and can have detrimental effects on human health and the environment.
In addition to its role as a pollutant, sulfur dioxide is also used in various industrial processes, including the production of sulfuric acid, bleaching agents, and preservatives. It is important to handle sulfur dioxide with care, as exposure to high concentrations of this gas can cause respiratory issues and other health problems.
