preparation of dilute nitric acid

An acid, which has a relatively low percentage of the acid in the aqueous solution, is classified as a dilute acid e.g. dilute hydrochloric acid, sulphuric acid, nitric acid, acetic acid et..

Zinc with dilute sulphuric acid is often used for the laboratory preparation of hydrogen. The reaction is slow at room temperature, but its rate can be increased by the addition of a little copper (II) sulphate. Zinc displaces copper metal, which acts as a catal..

. Hence the complete apparatus should be made of glass only. Although pure nitric acid is colourless, the acid obtained by this method is slightly yellowish brown. This is due to the formation of reddish brown fumes of nitrogen dioxide gas when the acid is ex..

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..

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

Hydrogen sulphide is the acid anhydrid..

Chemical Properties of Sulphuric Acid - As Dilute Acid - Sulphuric acid almost completely ionizes in water to form hydronium ions, sulphate ions, and hydrogen sulphate ions. The acidic properties of sulphuric acid are due to the presence o..

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..
