Which of the following statement is correct?
Zinc is more reactive than sodium
Copper is more reactive than zinc
Zinc is more reactive than iron
Iron is more reactive than zinc
C.
Zinc is more reactive than iron
(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
