Acid-base Behavior of the Oxides - Chemistry LibreTexts

The oxide ions are held too strongly in the solid lattice to react with the water. Reaction with acids: Aluminum oxide contains oxide ions, and thus reacts with acids in the same way sodium or magnesium oxides do. Aluminum oxide reacts with hot dilute hydrochloric acid to give aluminum chloride solution. [Al_2O_3 + 6HCl rightarrow 2AlCl_3 + 3H_2O]

Aluminum oxide | Al2O3 - PubChem

ALUMINUM OXIDE is chemically amphoteric (behaves as a weak acid in the presence of base and as a weak base in the presence of acid). May act catalytically. May cause the exothermic polymerization of ethylene oxide. May cause the vigorous polymerization of vinyl chloride [MCA SD-75, 1970]. The degree of subdivision of the aluminum oxide may affect the vigor of such reactions.

Corrosion & Chemical Changes in Aluminum Metal | Sciencing

The creation of aluminum oxide is an example of corrosion. The aluminum atoms lose electrons to oxygen atoms. However, the layer of aluminum oxide that forms on the surface of pure aluminum protects the aluminum below it from further corrosion. The aluminum can be protected even more by a thicker layer of aluminum oxide on a sample.
