* The manufacture of important fertilizers such as ammonium nitrate and basic calcium nitrate. * The manufacture of explosives like T.N.T, nitroglycerine, etc. * Manufacture of artificial silk, dyes and plastics, and nitro derivatives of organic compound..

Colour - Pure nitric acid is a colourless liquid. But commercial nitric acid may be yellowish brown, due to the presence of dissolved nitrogen dioxid..

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 present in ..

Nitric acid is a monobasic acid and may be structurally represented as,..

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 combine to form ..

In Free State - Nitric acid is present in small quantities in the atmosphere. But during thundershowers, a large quantity of this acid is produced in the atmosphere. It then comes down as a very dilute solution in rainwater. This nitric acid present..

Aqueous nitric acid obtained by this method can be concentrated by distillation to 68.5% by mass. Further concentration to 98% acid can be achieved by dehydration with concentrated sulphuric acid. Anhydrous nitric acid can be obtained by ..
