Write chemical equations that show aluminium oxide reacts with acid as well as base.

Ans:-Those metal oxides which show basic as well as acidic behaviour are known as amphoteric oxides. In other words, metal oxides that react wtih both acids and bases to form salt and water are called amphoteric oxides. Aluminium oxide and zinc oxide are amphoteric in nature.

Zinc oxide (ZnO) reacts with both acids and with bases:

In acid: $ZnO + 2 H^{+} \to {Zn}^{2} + + H^{2} O$

In base: $ZnO + H_{2} O + 2 {OH}^{-} \to {[Zn {(OH)}_{4} ]}^{2 -}$

Aluminium oxide

with acid: ${Al}_{2} O_{3 } + 3 H_{2} O + 6 H_{3} O^{+} (aq) \to 2 {[Al (H_{2} O) 6 ]}^{3 +}^{} (aq)$

with base: ${Al}_{2} O_{3} + 3 H_{2} O + 2 {OH}^{-} (aq) \to 2 [Al {(OH)}_{4}]^{-} (aq)$
