Oxides which shows both the properties of acids as well as bases are known as amphoteric oxides
Which react with both acids and basesEg-Alo3,zno2,etc
Those metal oxide which are basic as well as acidic in nature are called amphoteric oxides…….ex…..Zno
Metal oxides which behaves like both acid and base are called as amphoteric oxides, ex- zinc oxide
Metallic oxides which reacts with both acids and base to give salt n water is called amphoteric oxides.

Which shows both acidic& basic character
Which reacts with both acid and base

Amphoteric oxides : Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides. Such metallic oxides react with acids as well as base to produce salt and water. Examples of Amphoteric oxides are aluminium oxide ( Al2O3) and zinc oxide (ZnO).\xa0

The oxides which behaves both like acid and base that oxide is known as amphoteric oxide .Example – ZnO
