Answered by brainlessuser

Answer:

2. When zinc granules are added to the solution of copper sulphate, zinc displaces copper to form zinc sulphate and the copper gets deposited. In this reaction, zinc metal can easily displace the copper metal from its salt to form an aqueous solution of zinc sulphate.

3. Iron being more reactive displaces copper from copper sulphate solution. In this reaction, the blue colour of copper sulphate fades and there is deposition of copper on the iron nail.
