What does displacement reactionsmean?


  • Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.

  • Both metals and nonmetals take part in displacement reactions.

  • It can be represented generically as A + B - C → A - C + B.

  • This will most often occur if A is more reactive than B, thus giving a more stable product.

  • Examples include: Reaction of iron nails with copper sulphate solution. Fe+ CuSO4 --> Cu + FeSO4

  • Cu (s) + 2AgNO3  (aq) ---> Cu(NO3)2  (aq)  + 2Ag (s)

  • Examples include : Reaction of iron nails with copper sulphate solution. Fe+ CuSO4 --> Cu + FeSO4

  • Cu (s) + 2AgNO3  (aq) ---> Cu(NO3)2  (aq)  + 2Ag (s).
