Question

Describe an activity to show that iron is more reactive than
copper

Answer 1

Material required- Copper sulphate solution, Iron nail, test tube.

Method- In the test tube, pour copper sulphate solution. Drop the iron nails it and wait for the reaction to take place.

 

Observation- Solution turns blue. The nail which is in the contact with the solution turns reddish-brown. 

Conclusion- The above process can be understood by the following equation-

• Fe+CuSO4→FeSO4+Cu

This reaction is a type of displacement reaction.

Answer 2

Answer:

Procedure: take some copper sulfate solution (4-5 ml) in a test tube. Then immerse the iron filings or the iron nail in this solution. Wait for some time until the reaction happens. Hence, this activity shows that iron is more reactive than copper as it is able to displace copper in its aqueous salt solution.
