Answer:

Explanation:

(i): When it is heated in air, it combines with oxygen and gets rusted.

(ii): When added to dilute hydrochloric acid, the chloric ion will form an ionic bond with the metal and release hydrogen. However, not all metals would do since copper with hydrochloric acid has no reactions.

Therefore copper would be the most suitable for making saucepans.
