State which of the following chemical reactions will take place or not, giving suitable reason for each:
(i) Zn(s) + CuSO4 (aq) → ZnSO4(aq) + Cu(s)
(ii) Fe(s) + ZnSO4 (aq) → FeSO4(aq) + Zn(s)
(iii) Zn(s) + FeSO4(aq) → ZnSO4(aq) + Fe(s)
i) Zn(s) + CuSO4 (aq) → ZnSO4(aq) + Cu(s)
Reaction will take place as Zn is more reactive than copper. It displaces Cu from its solution.
ii) Fe(s) + ZnSO4 (aq) → NO REACTION
Reaction does not occur as iron is less reactive than Zn.
iii) Zn(s) + FeSO4(aq) → ZnSO4(aq) + Fe(s)
Reaction occurs because Zn is more reactive than iron.
