Question

An element forms an oxide A2O3 which is acidic in nature . Identify A as metal or non metal Give reason<br />​

Answer 1

Answer:

An element A which is given have the valency 3 and it is acidic in nature. if we take aluminum as a metal the aluminum ions are acidic in nature and thus it is proved that the A is a metal and thus an oxide is formed which is called aluminum oxide Al2O3.It is amphoteric in nature.It has a reaction as both base andAn element A which is given have the valency 3 and it is acidic in nature. if we take aluminum as a metal the aluminum ions are acidic in nature and thus it is proved that the A is a metal and thus an oxide is formed which is called aluminum oxide Al2O3.It is amphoteric in nature.It has a reaction as both base and acid.

Answer 2
