Question

write the reaction of Al with 1.dil.Hcl and 2.aq.NaoH​

Answer 1

Explanation:

A) Aluminium dissolves in NaOH forms soluble complex and liberates hydrogen gas.

2Al + 2NaOH + 6H2O → 2Na+[Al(OH)4-] + 3H2

B) Aluminium evolves hydrogen gas when heated with dil.HCl

2Al + 6HCl → 2AlCl3 + 3H2

Aluminium reacts with oxygen to form Alumina or aluminium oxide

4Al + 3O2 → 2Al2O3

Answer 2

A) Aluminium dissolves in NaOH forms soluble complex and liberates hydrogen gas.

2Al + 2NaOH + 6H2O → 2Na+[Al(OH)4-] + 3H2

B) Aluminium evolves hydrogen gas when heated with dil.HCl

2Al + 6HCl → 2AlCl3 + 3H2

Aluminium reacts with oxygen to form Alumina or aluminium oxide

4Al + 3O2 → 2Al2O3
