What happens when Zn strip is dipped in CuSO2 solution?

When a zinc (Zn) strip is dipped in a copper sulfate (CuSO₄) solution, a chemical reaction occurs.

  • Zinc reacts with copper sulfate: Zinc is more reactive than copper, so it displaces copper from the copper sulfate solution.
  • Formation of zinc sulfate and copper: The zinc strip dissolves, forming zinc sulfate (ZnSO₄), and copper (Cu) is deposited on the zinc strip.

The chemical reaction can be written as: Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)

This means that the zinc strip will gradually dissolve, and a layer of copper will form on the surface of the zinc.
