Class 10 Chemistry Chemical Reactions and Equations Displacement reaction

Displacement reaction

In displacement reaction a more reactive metal displaces a less reactive metal but a less reactive metal cannot displace a more reactive metal.

Let us take 5 beakers.

  • In beaker A Zn being more reactive than copper replaces copper from the solution of copper sulphate and forms zinc sulphate.

  • In beaker B iron being more reactive than copper replaces it from its solution and forms iron sulphate.

  • In beaker C there would be no reaction as less reactive metal (copper) cannot displace more reactive metal (zinc) from its solution.
  • In beaker D there would be no reaction as less reactive metal (copper) cannot displace more reactive metal (iron) from its solution.
  • In beaker E there would be no reaction as less reactive metal (iron) cannot displace more reactive metal (zinc) from its solution.
