Levels of SO2 higher than 10 mg/L must be labelled. The process can be used to analyze other beverages, such as wine. The. Uses: Sulfur dioxide, like Sulfur, is used as a fungicide. It has widespread toxic effects on microorganisms and is thus used to disinfect and to preserve food and wine. Dried fruits are also preserved with this because it prevents discoloration as well as preservation. In addition, it is extensively used in the brewing industry and as a bleaching agent for paper, textiles, oils, and more. Sulfur Dioxide (SO2)IntroductionSulfur dioxide is a gas that enters the atmosphere as a result of burning fossil fuels and from volcanic eruptions. In the atmosphere, sulfur dioxide reacts with water vapor, oxygen, and nitrogen oxides to create acid rain. When rain is acidic, it causes considerable damage to forests and to the ecosystems of freshwater bodies Sulfur trioxide (SO3) is generally a colorless liquid. It can also exist as ice- or fiber-like crystals or as a gas. When SO3 is exposed to air, it rapidly takes up water and gives off white fumes. It can react with water to form sulfuric acid.SO3 is also called sulfuric oxide and sulfuric anhydride
