Question

ditterence between displacements
and double displacement reaction? Give Suitable Chemical equations for the Same​

Answer 1

Displacement reaction is a reaction in which more reactive metal displace the less reactive metal.

For example

CuSO4 + Fe = FeSO4 + Cu

But double displacement reaction was occur between exchange of ions

For example

BaCl2 + Na2SO4 = BaSO4 + NaCl

Answer 2

In a displacement reaction, a more reactive element displaces a less reactive element from its compound whereas in a double displacement reaction, two compounds combine by an exchange of ions to form two new compounds.

1. A displacement reaction takes place between copper sulphate solution and zinc to form zinc sulphate solution and cooper: CuSO4(aq) + Zn(s) ---> ZnSO4(aq) + Cu(s)
2. A double displacement reaction takes place between barium chloride solution and sodium sulphate solution to form a white precipatate of barium sulphate and sodium chloride solution: BaCl2(aq) + Na2SO4(aq) ---> BaSO4(s) + 2NaCl(aq)
