✿$\textsf{\large{\underline{Question}:-}}$

The metal which produces hydrogen gas on reaction with dilute hydrochloric acid as well as sodium hydroxide solution is_________.

✿$\textsf{\large{\underline{Answer}:-}}$

$\textbf{Aluminium}$

The metal which produces hydrogen gas on reaction with dilute hydrochloric acid as well as sodium hydroxide solution is aluminium.

✿$\textsf{\large{\underline{Clarification}:-}}$

• Amphoteric metals are the metals that react with both acids and bases.Hydrogen is produced in this reaction.
• Aluminium oxide is amphoteric because it behaves as an acid with the base and vice versa thus,neutralising and producing a salt.
• Some other examples of amphoteric metals are zinc, tin, lead and beryllium.

✿$\textsf{\large{\underline{Reactions}:-}}$

Reactions discussed above are as follows:-

1)Reaction of Aluminium with NaOH

2Al + 2NaOH + 2H₂O → 2NaAlO2 + 3H2

☆Sodium hydroxide is a base.

2.Reaction of Aluminium with HCl

2Al+ 6HCl→2AlCl3 + 3H2

☆Hydrochloric acid is a base.

Hydrogen gas is produced when aluminium metal reacts with sodium hydroxide solution.Sodium aluminate and hydrogen gas are products formed.

✿$\textsf{\large{\underline{Other important facts}:-}}$

• Non-metallic oxides are usually acidic and the metallic oxides are basic.
• Elements that form amphoteric oxides have some metals and some of the non-metals characteristics.
• Amphoteric oxides are considered as metal oxides that react with both acids as well as bases to produce salts and water.
• Other example of amphoteric reaction is as follows—

ZnO(s) + 2HCl(aq) → ZnCl2(aq) + H2O(l)

ZnO(s) + 2NaOH(a) → Na2ZnO2(aq) + H2O(l)
