Answer 2

Answer:  

When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the color of copper sulphate solution changes from blue to light green. This reaction shows that iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe  2+  ions and ferrous sulphate solution is formed.
