Solution:
Iron reacts with copper sulphate solution to produce copper and ferrous sulphate. Copper separates out of the solution while ferrous sulphate remains in solution. The following reaction in the form of a chemical equation isIf an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed in the surface of iron. And the colour of copper sulphate solution changes from blue to pale green. The reaction indicates that iron is more reactive than copper because it displaces copper from the copper sulphate solution. Iron () reacts with copper sulphate () to form copper () and ferrous sulphate ().
This reaction is an example of displacement reaction.
