Question

Al2O3 is an atmospheric oxide.Show it's acidic and basic behaviour by suitable reactions .​

Answer 1

Answer:

Correct Question→

$\rm{Al_2O_3}$ is an amphoteric oxide. Show it's acidic and basic behavior by suitable reaction.

Answer→

1. Acidic Behavior:-

Aluminium Oxide $\rm{(Al_2O_3)}$ while reacting with a base, acts as an acid.

REACTION:-

$\rm{Al_2O_3(s)+2NaOH(aq)\xrightarrow{~}2NaAlO_2(aq)+H_2O(l)}$

2. Basic Behavior:-

Aluminium Oxide $\rm{(Al_2O_3)}$ while reacting with an acid, acts as a base.

REACTION:-

$\rm{Al_2O_3(s)+6HCl(aq)\xrightarrow{~}2Al_2O_3(aq)+3H_2O(l)}$

Amphoteric Oxides: Those oxides that can react with acids as well as bases are are called amphoteric oxides.

Some more examples of amphoteric oxides are ZnO, PbO, SnO etc.
