The correct answer is displacement.Key Points

  • The reaction Fe + CuSO4 -> FeSO+ Cu involves the displacement of copper from copper sulfate by iron.
  • This is because iron is more reactive than copper and can displace it from its compound.
  • This is an example of a displacement reaction, which is a type of redox (reduction-oxidation) reaction where there is a transfer of electrons between the reactants.

Additional Information

  • Neutralisation reactions involve the combination of an acid and a base to form a salt and water. 
  • Reversible reactions are those that can proceed in both the forward and reverse directions.
    • The given reaction is not reversible as it proceeds in only one direction.
  • Iron is a chemical element with the symbol Fe and atomic number 26.
    • It is a metal and is found in many minerals, including hematite and magnetite.
    • Iron is used in the production of steel, which is an important material in construction and manufacturing.
