________ is displaced when zinc is added to the solution of copper sulphate.

When zinc is added to a solution of copper sulphate, copper is displaced. This is because zinc is more reactive than copper and can replace copper in the solution. The chemical reaction is: Zn(x) + CuSO4(aq) → ZnSO4(aq) + Cu(s). In this displacement reaction, zinc displaces copper from copper sulphate, forming zinc sulphate and solid copper.
