Write an activity about how you conduct an experiment to show that more reactive metals metals replace less reactive metals from their compounds.

Explanation

1) Take two iron nails and clean then by rubbing with sand paper.
2) Take two test tubes and mark them 'A' and 'B'.
3) Pour copper sulphate solution in the test tube 'A' and Zinc Chloride solution in the test tube 'B' .
4) Dip iron nails in both test tubes.
5) Keep them without disturbing for 20 min.
Observation :
1) The nail which is dipped in Copper Sulphate solution becomes brownish colour.
2) The nail which is dipped in Zinc Chloride solution doesn't change .
Reaction `:" In test tube 'A' : "CuSO_(4)+Fe rarr FeSO_(4)+Cu`
`" In test tube 'B' : "ZnCl_(2)+Fe rarr "No reaction."`
Conclusion :
1) Iron is more reactive than copper. So it displaces copper from Copper Sulphate solution.
2) Iron is less reactive than zinc. So, it doesn't displace zinc from `ZnCl_(2)`.
