The reaction in which the place of the ion of a less reactive element in a compound is taken by another more reactive element by formation
of its own ions,is called displacement reaction.
Zn(s)+CuSO4(aq) = ZnSO4(aq)+Cu(s)
In the above equation when zinc dust is added
to blue coloured copper sulphate solution, a
colourless solution of zinc sulphate is formed and copper is deposited on zinc.The Zn (2+)
ions formed from zinc atom take the place of Cu(2+) ions in copper sulphate and Cu atoms formed from Cu(2+) ion come out.It means that Zinc displaced Copper from CuSO4.
