Answer:
The displacement reaction, one element displaces another from a compound and takes its place in the compound.
The displacement of copper from copper sulphate by iron.
When an iron knife or nail is placed in a copper sulphate solution, there is a brown-red deposit of copper over the iron object. After some time, the Blue color of the solution changes to green. This happens because iron(II) sulphate is formed.
