Acid Rain - Department of Chemistry

Nitric oxide (NO), which also contributes to the natural acidity of rainwater, is formed during lightning storms by the reaction of nitrogen and oxygen, two common atmospheric gases (Equation 3). In air, NO is oxidized to nitrogen dioxide (NO 2) (Equation 4), which in turn reacts with water to give nitric acid (HNO 3) (Equation 5).
