Answer 1

Activity :

Take some Iron fillings and dip them in the Copper sulphate solution. After some time you will notice that there is a colour change in the solution which is caused due to the displacement of Copper from it solution. This shows that Iron is more reactive than Copper.

Hope it's help you dear..

Answer 2

HEY MATE...HERE'S YOUR ANSWER...!!

Aim- To show that iron(Fe) is more reactive than copper(Cu).

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

Thsi reaction is a type of displacement reaction.
