What are amphoteric oxides ? Give two examples with equations.
Answers
An amphoteric oxide is one that can act as either an acid or a base.Amphoteric oxides react with both acids and alkalis to form salt and water. Examples of amphoteric oxides are zinc oxide and aluminum oxide.
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 and zinc oxide.
Amphoteric oxides are defined as the oxides which can act like the acid and also base for producing water and salt. It can accept or donate the proton or H+ ion therefore appearing as an acid or a base.ZnO (zinc oxide) is a major example of the amphoteric oxide.
Explanation:
An amphoteric oxide is one that can act as a base or as an acid. The non-metallic oxides are generally acidic and the metallic oxides are basic. ... Amphoteric oxides react with both acids and alkalis to form salt and water. Examples of amphoteric oxides are zinc oxide and aluminum oxide.
