Answer:
luminium oxides are known to be amphoteric because they can act as either an acid or a base in an acid-base reaction. Amphoteric compounds refer to these compounds that can react with both acids and bases.
For example, aluminium oxide reacts with hydrochloric acid to give water and aluminium chloride. In this reaction, aluminium oxide plays the role of base.
Aluminium oxide can also react with sodium hydroxide, a base, to give water and sodium aluminate (NaAlO3). In this reaction, aluminium oxide instead plays the role of acid.
