Amphoteric Oxides: Learn Identification, Properties & Application Amphoteric oxides are compounds that react with both acids and bases to form salts and water. Numerous metals, including beryllium, zinc, tin, lead, and aluminium, can create amphoteric oxides or hydroxides. An example of an amphoteric oxide is A l 2 O 3. The oxidation states of the oxide highly determine amphoterism.
