Toppr Admin · Accepted Answer

Aluminium is amphoteric in nature as it reacts with acids as well as alkalies- 2Al-6HCl-x2192-2Al3-6Cl-x2212-3H22Al-2NaOH-6H2O-x2192-2Na-Al-OH-4-x2212-3H2

Write reactions to justify amphoteric nature of aluminium.

Aluminium is amphoteric in nature as it reacts with acids as well as alkalies.
$2 A l + 6 H C l \to 2 A l^{3 +} + 6 C l^{-} + 3 H_{2}$
$2 A l + 2 N a O H + 6 H_{2} O \to 2 N a [A l (O H)_{4}]^{-} + 3 H_{2}$

Write reactions to justify amphoteric nature of aluminium.

Aluminium is amphoteric in nature as it reacts with acids as well as alkalies. 2Al+6HCl→2Al3++6Cl−+3H22Al+2NaOH+6H2O→2Na[Al(OH)4]−+3H2
