Question

why is aluminum oxide called amphoteric ​

Answer 1

Answer:

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.
