Displacement Reaction

Chemistry
Concept:Displacement Reaction

The reaction in which an element, displaces another element from its compound, is called Displacement Reaction. The element that displaces, is more reactive than the element being displaced.

Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) (1.24)
(Copper sulphate) (Iron sulphate)
In this reaction, iron has displaced or removed another element,
copper, from copper sulphate solution.




Other examples of displacement reactions are
Zn(s) + CuSO4(aq)→ ZnSO4(aq) + Cu(s) (1.25)
(Copper sulphate) (Zinc sulphate)
Pb(s) + CuCl2(aq) → PbCl2(aq) + Cu(s) (1.26)
(Copper chloride) (Lead chloride)
Zinc and lead are more reactive elements than copper. They displace
copper from its compounds.

Displacement reactions are carried out to make a series of metals according to their reactivity. This is called Reactivity series.
