normality of conc. nitric acid

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

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..

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..

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. Then nitroge..
