Which substance is deposited on the surface of zinc when it is placed in copper sulphate solution?

Answer and explanation

Correct answer: Copper

Zinc is more reactive than copper, so it displaces copper from copper sulphate solution:
\(\mathrm{Zn + CuSO_4 \rightarrow ZnSO_4 + Cu}\)
The released copper is deposited as a reddish-brown solid on the zinc surface. Zinc sulphate is formed in the solution, so it is not the deposited solid.
