Solution

Cu(s) + FeSO4(aq) → No change will take place .

Copper is less reactive then Fe so, Cu cannot displace iron from ferrous sulphate solution

* No reaction will take place.

2Al(s) + 3FeSO4(aq) → Al2(SO4)3 + 3Fe(s)  (Displacement reaction) 

* When Al is added to a FeSO4 (aq) solution , the freen colour of FeSO4(aq)  disappears and the Fe is seen setting down as the reaction accurs Al being higher in reacting series displace the Fe in FeSO4

  Is there an error in this question or solution?
