nitric acid preparation

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 but less volatile acid such as concentrate..

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..

The important uses of nitric acid are as follows: 1) Nitric acid plays a significant role in the manufacture of various products such as: Explosives like trinitrotoluene (T.N.T.) nitro glycerine, gun cotton, ammonal etc. Fertilizers such as calcium nitra..

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