a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green.
Explanation:
Because, iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe (II) ions and ferrous sulphate solution is formed
