उत्तर
\[\ce{Cu(s) + FeSO4(aq) -> No change will take place}\]
Copper is less reactive than Fe, so Cu cannot displace iron from a ferrous sulphate solution.
No reaction will take place.
\[\ce{2Al(s) + 3FeSO4(aq) -> Al2(SO4)3 + 3Fe(s)}\] (Displacement reaction)
When Al is added to a FeSO4(aq) solution, the green colour of FeSO4(aq) disappears and the Fe is seen setting down as the reaction occurs Al being higher in the reacting series displaces the Fe in FeSO4.
