    A student performed the first set of experiments with four test tubes containing solutions and metal pieces as indicated in the figure. In the second set of experiments, the metal pieces are interchanged between test tubes P and Q and also between test tubes R and S.

    Certain metals have the capacity to displace some metals from their salt solutions. These reactions are known as metal displacement reactions. A metal placed higher in activity series can displace the metal occupying lower position from aqueous solution of its salt or a more reactive metal can displace less reactive metal from its salt solution. Q. Take aqueous solution of copper sulphate in one test tube and ferrous sulphate in another test tube. dip an iron nail in copper sulphate and copper wire in ferrous sulphate solution. mark the correct observation.
