Why the aluminium oxides is called amphoteric oxides

Aluminium 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.

In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid and as a base.Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. AlO is an example of an amphoteric oxide.as all is forming basic and acidic salts so it is known as amphoteric oxide.
