animation of nitric acid preparation

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

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..

Discovery of Nitric Acid - 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..

Tests for Nitric Acid and the Nitrates - Various tests for nitric acid and nitrates are mentioned bel..

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

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 nitric oxide. Th..

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 in the ..

A sample of nitric acid gives the following test..
