Sulfuric acid burns can be very painful and cause serious damage upon contact, according to WebMD. Generally, a small fraction of sulfur (S) in coal is converted to SO 3 in coal-fired combustion devices such as electric utility boilers. It can react with water to form sulfuric acid. 2 Names and Identifiers. D.K. WS4550000. Sulfur trioxide 1 Structures.

An entry published on the open chemistry database Pub Chem reveals that the harmful chemical is commonly used as a preservative and as a disinfectant for food containers and fermentation equipment. Articles of sulfur trioxide are included as well. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. When SO3 is exposed to air, it rapidly takes up water and gives off white fumes. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Consequently, these emissions need to be low enough to not cause opacity violations and acid deposition. Sulphur dioxide and trioxide poisoning – the facts Sulphur dioxide and sulphur trioxide are potentially fatal gases.
6 Pharmacology and Biochemistry. Emissions of sulfur trioxide (SO 3) are a key component of plume opacity and acid deposition.
Sulfur dioxide (also sulphur dioxide in British English) is the chemical compound with the formula S O 2.It is a toxic gas responsible for the smell of burnt matches.It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of fossil fuels contaminated with sulfur compounds. Sulfur dioxide is a colorless but otherwise pungent air pollutant that is highly toxic to both human and environmental health. It is a by-product of ore smelting coal, and fuel-oil combustion, paper manufacturing, and petroleum refining (WHO 1984).
Synonyms & Trade Names Sulfur oxide, Sulfurous acid anhydride, Sulfurous oxide CAS No.
It reacts violently with water to form sulfuric acid with the release of heat.
Often shipped with inhibitor to prevent polymerization.
