industrial preparation of nitric acid

On a commercial scale, nitric acid is manufactured through the Ostwald's process - the process of catalytic oxidation of ammoni..

Paper industries - For e.g., chlorinated effluents Textile industries - For e.g., Ammoniated effluents Thermal plants - For e.g., Hot water Fertilizer, food and chemical industries - For e.g., acidic / corrosive effluents Petroleum industri..

The most important and useful oxoacid of nitrogen is nitric acid. Its molecular formula is HNO 3 and molar mass 53 g mol - 1..

From Ammonical Liquor - During the destructive distillation of coal, ammonical liquor is obtained as a by-product. Ammonical liquor on further processing yields large quantities of ammonia and ammonium salts. Ammonical liquor is boiled with milk of lime to obtain ammonia. This is passed into ice-co..

Preparation of Nitric Acid - Nitric acid can be prepared by distilling a mixture of a nitrate salt with concentrated sulphuric acid. As nitric acid is a volatile acid it can be expelled by a stronger..

Various tests for nitric acid and nitrates are mentioned bel..

Johann Glauber (1604-1668) prepared nitric acid by heating nitre with concentrated sulphuric acid and then condensing the vapour. While Henry Cavendish determined the composition of nitric acid, Lavoisier proved that oxygen is presen..

Nitric acid from Air - Nitric acid can also be prepared entirely from the air. Air free from moisture and carbon dioxide is subjected to an electric arc whose temperature is around 3000 o C. At this temperature, nitrogen and oxygen of the air combin..
