  • 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.

    A
    Blue colour in first test tube changes to light green and green in the second test tube changes to blue
    B
    There is no reaction in both the test tubes.
    C
    Blue colour in first test tube changes to light green and no change in second test tube
    D
    Blue colour remains as such and green colour in second test tube changes to blue
