Cu(s) +FeSO_{4}(aq) \rightarrow No \; change\; will\; take\; place

Copper is less reactive than Fe So, Cu cannot displace iron from ferrous sulphate solution

No reaction will take place.

2Al(s) +3FeSO_{4}(aq)\rightarrow Al_{2}(SO_{4})_{3}+3Fe(s)

        (Displacement reaction)

When Al is added to FeSO_{4} solutionm the green colour of FeSO_{4} disappear and Fe is seen setting down as reaction occurs. Al being higher in reacting series displace Fe in FeSO_{4}.
