Explain the unique nature of zinc and aluminium give balanced equations to support your explanation
Answers
Answer: The equations of the following reactions are given below.
Explanation:
Aluminium and Zinc are the elements which lie above in the reactivity series.
These two metals show amphoteric nature because they react with acid and base both.
- Reactions of Zinc with acid and base follows:
With acid:
When zinc reacts with hydrochloric acid, it produces zinc chloride and hydrogen gas.
With base:
When zinc metal reacts with sodium hydroxide, it produces sodium zincate and hydrogen gas.
Zinc with acid and base produces a salt and releases hydrogen gas.
- Reactions of Aluminium with acid and base follows:
With acid:
When aluminium reacts with hydrochloric acid, it produces aluminium chloride and hydrogen gas.
With base:
When aluminium reacts with sodium hydroxide, it produces sodium aluminate and hydrogen gas.
Aluminium with acid and base produces a salt and releases hydrogen gas.
