Sulfur dioxide
Sulfur dioxide (chemical formula: SO2) is a chemical compound that is a toxic gas with a pungent, irritating smell. It is released naturally by volcanic activity and is produced as a by-product of the burning of fossil fuels contaminated with sulfur compounds.
Chemical properties[edit]
Sulfur dioxide is a bent molecule with C2v symmetry point group. A significant amount of the sulfur dioxide produced in the atmosphere is the result of the reaction between sulfur and oxygen.
Uses[edit]
Sulfur dioxide is an important compound in many industries. It is used in the production of sulfuric acid, one of the most important chemicals manufactured by the chemical industry. It is also used as a preservative in some foods, particularly dried fruits, and as a reducing agent in brewing and winemaking.
Health effects[edit]
Exposure to sulfur dioxide can have various health effects. It can cause a burning sensation in the nose and throat, difficulty breathing, and severe airway obstructions. Chronic exposure to sulfur dioxide can cause respiratory problems and alterations in the lungs' defenses.
Environmental impact[edit]
Sulfur dioxide is one of the major air pollutants and a significant contributor to acid rain. When it reacts with water, it forms sulfurous acid, which is a component of acid rain.
