 Sulfur dioxide is a colorless gas with a suffocating, choking odor.  It is toxic to humans and concentrations as low as 8 ppm will produce coughing.    In the gaseous form, this species is a significant pollutant, being the primary agent in acid rain. It is prepared on massive scales as a precursor to sulfuric acid.Both oxides are acidic
