Nitric Acid

NITRIC ACID
Manufactured:
Nitric acid is manufactured by oxidation of ammonia followed by treatment with water. Ammonia and air are passed over a heated platinum catalyst at 900 degrees centigrade. An exothermic reaction takes place producing nitrogen monoxide and steam. The mixture of gases is cooled and nitrogen monoxide reacts with further oxygen in the air to produce nitrogen dioxide: The nitrogen dioxide is then mixed with more air and passed up a tower down which water flows. The water reacts with th…
