Question

What will you observe when some zinc pieces are putting in the copper solution?

Answer 1

As Zinc is more reactive than copper, zinc displaces copper from copper sulphate & forms zinc sulphate solution. This is indicated by colour change from blue to colourless. CuSO4 solution has a blue colour while ZnSO4 solution is colourless. Zn(s) + CuSO4(aq) -> Cu(s) + ZnSO4 (aq).

Answer 2

Reason Zinc reacts with copper sulphate to form colourless zinc sulphate solution and solid copper in deposited form.
