Question

What is amphoteric oxide?give suitable chemical equation

Answer 1

Hey friend,

Here is your answer,
______________________________________________________________

Amphoteric oxides are that type of oxides which act as acid when they react with base and as base when they with react acid.


Examples:-

ZnO (Zinc Oxide) is an amphoteric oxide.


ZnO  +  2HCl    --------->     ZnCl₂  +  H₂O

Here ZnO acts as a base which reacts with acid (HCl) to form a salt (ZnCl₂) and water.


ZnO   +   NaOH   ---------->   Na₂ZnO₂   +   H₂O

Here ZnO acts as acid which reacts with a base (NaOH) to form a salt (Na₂ZnO₂) and water.



Another amphoteric oxide is Al₂O₃ (Aluminium Oxide).

Al₂O₃   +   HCl     ----------->     AlCl₃  +   H₂O

Here Al₂O₃ acts as base which reacts with Acid (HCl) to form a salt (AlCl₃) and water.


Al₂O₃   +   NaOH    --------->    NaAlO₂  + H₂O

Here Al₂O₃ acts as acid which reacts as base (NaOH) to form a salt (NaAlO₂) and water.

Answer 2

Answer:

Amphoteric oxides can be defined as oxides that can behave as an acid as well as a base to produce a salt and water. It can either donate or accept a proton or H+ ion thus acting as base or an acid.
