Question

write reaction to justify amphoteric nature of aluminium?​

Answer 1

Hey mate..✌

The amphoteric nature of the element explains that it can react with both acids and bases. Aluminium dissolves in mineral adds and aqueous alkalies and thus shows amphoteric character. Aluminium dissolves in dilute HQ and liberates dihydrogen.

Answer 2

Al2O3(S)+2NaOH(aq)--------->2NaAlO2(aq)+H2O(l)

Where NaAlO2 is a salt, Al2O3 is aluminum oxide(amphoteric oxide) and NaOH is a base......

And also Al2O3 reacts with acids to form a salt and water...

Hope this helps you.....
