Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions.
The following chemical reaction takes place in this Activity–
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
In this reaction, iron has displaced or removed another element copper, from copper sulphate solution. This reaction is known as displacement reaction. Other examples of displacement reactions are
Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)
Pb(s) + CuCl2(aq) → PbCl2(aq) + Cu(s)
Zinc and lead are more reactive elements than copper. They displace copper from its compounds.
