Aluminium nitrate is not easily made by adding aluminium to nitric acid, as the aluminium forms a passivation layer.
Aluminium nitrate nonahydrate can also be made by adding a lead nitrate solution to an aluminium sulfate solution. The insoluble lead sulfate is precipitated out of the solution, leaving a solution of aluminium nitrate.
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 aluminium nitrates have many applications. These salts are used to produce alumina for preparation of insulating papers, in cathode ray tube heating elements, and on transformer core laminates. The hydrated salts are also used for the extraction of actinide elements.
It is used in the laboratory and classroom such as in the reaction:
Al(NO3)3 + 3NaOH → Al(OH)3 + 3NaNO3
