Question

Iron is more reactive than copper. Describe an experiment to prove this. in 80 to 90 words​

Answer 1

Answer:

Iron is more reactive than copper, this can be proved with an activity.

Materials required for the activity: copper sulfate solution, iron filings or iron nail, test tube.

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.

Observation: after sometime it will be observed that the blue color copper sulfate solution turns pale green in color. This is due to the displacement of copper from copper sulfate to iron. The reaction that happens is a displacement reaction that is-

Fe+CuSO4→FeSO4+Cu

Hence, this activity shows that iron is more reactive than copper as it is able to displace copper in its aqueous salt solution.

Answer:

Materials required for the activity: copper sulfate solution, iron filings or iron nail, test tube.

Observation: after sometime it will be observed that the blue color copper sulfate solution turns pale green in color. This is due to the displacement of copper from copper sulfate to iron. The reaction that happens is a displacement reaction that is-

Fe+CuSO4→FeSO4+Cu

Hence, this activity shows that iron is more reactive than copper as it is able to displace copper in its aqueous salt solution.

Note:

If we reverse the activity by adding copper to the iron sulfate solution, then no change will happen. This is because iron is more reactive and copper being less reactive cannot displace iron from its aqueous salt solution. The reactivity series shows the placing of iron above copper, so iron is more reactive than copper.
