Solution

Displacement reaction:

  • A displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.
  • In other words, the displacement reaction is known as the reaction where the element with more reactiveness usually displaces the substance which is less reactive from its salt solution.

The type of the given reaction:

  • The reaction is given as:

CuSO4(aq)CoppersulfateBlue+Zn(s)ZincCu(s)Copper+ZnSO4Zincsulfate(aq)(Colorless)

  • It is an example of a displacement reaction.
  • A displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.
  • In the above reaction, Zn is added to the solution of Copper sulfate which displaces Cu from its salt solution.
  • This happens due to reason as Zinc which is known as a more reactive metal displaces the less reactive metal i.e Copper from its solution.
  • The reaction is also indicated by a color change from blue to colorless.
  • Where the CuSO4 solution having a blue color undergoes a change into the ZnSO4solution which is colorless.

Hence, CuSO4(aq)+Zn(s)Cu(s)+ZnSO4(aq) is an example of a displacement reaction.
