Sulfur dioxide is a colourless gas with a pungent smell which has a molecular weight of 64.06. Its melting point is −75.7 °C, the boiling point −10 °C. Most of the sulfur dioxide produced is further processed to form sulfuric acid. Sulfur dioxide is used in the paper industry during the sulfite process.
