How is sulphur trioxide formed
WebSulfur 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 … WebSulfur trioxide is formed in the air by oxidation of the lower oxide. In the presence of water vapor, sulfur trioxide immediately reacts to form sulfuric acid, which remains suspended in droplets in the air. Sulfur dioxide and sulfur trioxide are both strongly irritating to the respiratory tract.
