Aluminium nitrate is a salt of aluminium and nitric acid, existing normally as a crystalline hydrate, most commonly as aluminium nitrate nonahydrate, Al(NO3)3·9H2O, with a molecular formula weight of 327.124 g/mol.
Preparation
Aluminium nitrate cannot be made by adding aluminium to nitric acid, as the aluminium forms a passivation layer.
To make aluminium nitrate, just add nitric acid to aluminium trichloride, and the by-product, nitrosyl chloride, will bubble out of the solution.
Aluminum nitrate nonahydrate can also be made by adding a lead nitrate solution to an aluminum sulfate solution. The insoluble lead sulfate is precipitated out of the solution, leaving a solution of aluminum nitrate.
Uses
Aluminium nitrate is a strong oxidizing agent. It is used in tanning leather, antiperspirants, corrosion inhibitors, extraction of uranium, petroleum refining, and as a nitrating agent.
The nonahydrate and other hydrated aluminum nitrates have many applications. These salts are used to produce alumina for preparation of insulating papers, in cathode tube heating elements, and on transformer core laminates. The hydrated salts are also used for the extraction of actinide elements.[1]
It is used in the laboratory and classroom such as in the reaction:
Al(NO3)3 + 3NaOH → Al(OH)3 + 3NaNO3
