Question

Metal A burns in air, on heating,to form an oxide A2O3, whereas another metal B burns in air only on strong heating to form an oxide BO. The two oxides A2O3 and BO can react with Hydrochlroric acid as well as Sodium Hydroxide solution to form the corresponding salts and water.What is the nature of oxide A2O3

Answer 1

A and B are amphoteric oxides

Answer 2

Answer: Amphoteric in nature

Explanation:

Since both oxides $A_2O_3$ and BO can react with Hydrochloric acid as well as Sodium Hydroxide solution to form the corresponding salts and water, it means they can react with both acid and base to form salt.  

The compounds which can react with both acid and base and undergo neutralization to form salt and water are called as amphoteric compounds.

Hence, the nature of oxide $A_2O_3$ is amphoteric nature.
