'''Aluminium nitrate''' is a [[Salt (chemistry)|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 212.996 g/mol.

==Preparation==

Aluminium nitrate is not easily made by adding aluminium to nitric acid, as the aluminium forms a [[passivation]] layer.

Aluminium nitrate is made by adding nitric acid to [[aluminium trichloride]]. [[Nitrosyl chloride]] is produced as a by-product; it bubbles out of the solution as a gas.

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 ray tube]] heating elements, and on transformer core laminates. The hydrated salts are also used for the extraction of [[actinide]] elements.<ref>Pradyot Patnaik. ''Handbook of Inorganic Chemicals''. McGraw-Hill, 2002, ISBN 0-07-049439-8</ref>

It is used in the laboratory and classroom such as in the reaction:

Al(NO₃)₃ + 3NaOH → Al(OH)₃ + 3NaNO₃
