WebbNitric acid is made by reaction of nitrogen dioxide ( NO2) with water . 4 NO2 + 2 H2O → 2 HNO3 + NO + NO2 + H2O The net reaction is: 3 NO2 + H2O → 2 HNO3 + NO Normally, the nitric oxide produced by the reaction is reoxidized by the oxygen in air to produce additional nitrogen dioxide. Webb8.8 Nitric Acid 8.8.1 General 1-2 In 1991, there were approximately 65 nitric acid (HNO 3) manufacturing plants in the U. S. with a total capacity of 11 million tons of HNO 3 per year. The plants range in size from 6,000 to 700,000 tons per year. About 70 percent of the nitric acid produced is consumed as an intermediate in the manufacture of
