What is Bauxite?
The typical ore of aluminium is bauxite (Al 2 O 3.2H 2 O). Amphoteric oxides are also classified as metal oxides that react with both acids as well as bases to create salts and water. Al 2 O 3 is, for example, an amphoteric oxide. An amphoteric compound is a molecule or ion that may react to create salt and water from both an acid and a base.
