Present-day nitric acid production is almost entirely via the oxidation of ammonia and absorption of the oxidation products in water. The chemistry of this process was proven experimentally by Kuhlmann in 1839, but had to wait for the development of an economical route to ammonia before it could become commercially significant [38].Ostwald, working …

NITRIC ACID PRODUCTION Nitric acid is almost always made by mixing gaseous ammonia with air, converting it to nitric oxide (NO) in a reactor over a platinum-rhodium catalyst at 800–950 °C (1470–1740 °F), and further oxidizing the NO to NO 2. The nitric oxide is passed through an absorber column for conversion to 60–65% HNO 3

Nitric acid is one of the strongest oxidizing agents as it attacks almost all metals (except gold and platinum). The reason for nitric acid being one of the strong acids is that when it is dissolved in water, the molecules of nitric acid dissociate into Hydrogen ions ( H+) and nitrate ions (NO 3). The dissociation of nearly every molecule of ...
