Answer:
1. When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green.
3. when a rod of zinc metal is dipped into a solution of copper sulphate then the zinc reacts with it and displaces the copper. its colour will change from Blue to colourless in the meanwhile copper sulphate is blue and Zinc is colourless.
