Acid Rain - Washington University in St. Louis

Sulfur dioxide, like the oxides of carbon and nitrogen, reactswith water to form sulfuric acid (Equation 6). (6) Sulfuric acid is a strong acid, so it readilydissociates in water, to give an H+ion and an HSO4-ion (Equation 7). The HSO4-ion may furtherdissociate to give H+and SO42-(Equation 8).
