(a) Observe the following figure,(a) and (b) and complete the reaction and tell in which beaker/beakers displacement reactions take place.
(ii) Arrange Zinc, Aluminium, Iron and Copper in the decreasing order of reactivity.
(a)
Beaker A : Copper Sulphate (CuSO4) + Zinc granite (Zn)
Beaker B : Copper Sulphate (CuSO4) + Iron nail (Fe)
Beaker C : Zinc Sulphate (ZnSO4) + Copper turnings (Cu)
Beaker D : Iron Sulphate (FeSO4) + Copper turnings (Cu)
Beaker E : Zinc Sulphate ZnSO4) + Iron nail (Fe)
(b)
Beaker A : Copper Sulphate + Zinc → Zinc Sulphate + Copper
Beaker B : Copper Sulphate + Iron → Ferrous Sulphate + Copper
Beaker C : Zinc Sulphate + Copper → No reaction
Beaker D : Iron Sulphate (FeSO4) + Copper turnings → No reaction
Beaker E : Zinc Sulphate (ZnSO4) + Iron (Fe) → No reaction
In beakers A and B displacement reaction takes place.
(ii)
Aluminium > Zinc > Iron > Copper
