Displacement Reaction

The displacement reaction is one in which one element displaces another element from its compounds.

For example,

Fe (s) + CuSO₄ (aq) → FeSO₄ (aq) + Cu (s)

Iron has displaced copper from copper sulphate solution.

Other Examples

Zn (s) + CuSO₄ (aq) → ZnSO₄ (aq) + Cu (s)

Pb (s) + CuCl₂ (aq) → PbCl₂ (aq) + Cu (s)

Since zinc and lead are more reactive metals than copper, therefore they displace copper from its compound.
