CuSO4+Zn== ZnSO4+ Cu
CuSO4+Fe== FeSO4+ Cu
ZnSO4+Fe=== no reaction
ZnSO4+Cu=== no reaction
Formation of sulphate and individual metal as precipitate gave hint towards displacement reaction.
Explanation:
X Sulphate= CuSO4
Y sulphate= ZnSO4
Z sulphate= FeSO4
The reactions in question is an example of displacement reaction. In these reactions one element displaces another element or metal in a compound.
From the reactions the metals are Cu, Zn, Fe
Displacement reaction is a type of chemical reaction in which a more reactive element or metal displaces a less reactive element from its compound.
The formation of sulphate and the free metal in the product gave hints for the reaction to be grouped in displacement reaction. The activity of the metals can be known from activity the series.
we can conclude that Zinc can displace Cu, Fe can displace Cu.
