Write reactions to justify amphoteric nature of aluminium .

Text Solution

Verified by Experts

Aluminium dissolves in both acids and alkalies . Aluminium dissolves in dilute HCl and liberates dihydrogen
`2Al+ 6HCl to 2AlCl_3 + 3H_2`.
Aluminium also dissolves in aqueous alkali and liberates dihydrogen.
`2Al+2NaOH + 6H_2O to 2Na^(+) [Al(OH)_4]^(-) + 3H_2`
These reactions indicate the amphoteric nature of aluminium.
