Question

Take two conical flasks. Label them as I and II. 

Take a small amount of copper sulphate solution in the first conical flask. Take a small amount of granulated zinc in the second conical flask. Allow the copper sulphate solution to react with the zinc. 

1. Name the type of reaction. 

2. Say whether the metal zinc is more reactive or less reactive. 

3. Write a complete and balanced reaction. 

4. Say whether this change is reversible or irreversible.

Answer 1

1. The reaction taken place is displacement reaction. 

2. Metal zinc is more reactive. 

3. Balanced chemical equation. 

Zn_(s) + CuSO_4(aq) → ZnSO_4(aq) + Cu_(s)

4. This change is an irreversible change.
