Question

Which metal reacts most with dilute acid to displace hydrogen?

• A. Zinc
• B. Copper
• C. Silver
• D. All react the same

Hint:

Metals higher in the reactivity series (like Zinc) react more readily with dilute acids to displace hydrogen.

Answer 1

The Correct Option is A

Step 1: Understanding reactivity with dilute acids.
The reactivity of a metal with dilute acid to displace hydrogen is governed by its position in the reactivity series. Metals higher in the reactivity series displace hydrogen more readily.
Step 2: Comparison of metals.
- Zinc (Zn) is a highly reactive metal and reacts readily with dilute acids like HCl to release hydrogen gas. - Copper (Cu) and Silver (Ag) are much less reactive and do not react with dilute acids to displace hydrogen under normal conditions.
Step 3: Conclusion.
Thus, Zinc reacts most with dilute acid to displace hydrogen, corresponding to option (A).
