Question

show with the help of an activity...
Iron is more reactive than copper..

 

Answer 1

take a beaker . pour some copper sulphate solution in it. take some iron nails and put them into the copper sulphate solution . leave the solution undisturbed for few days . you will notice that the blue colour of copper sulphate solution has turned a dirty green this happened due to iron being more reactive than copper displaced it from its sulphate solution and formed iron sulphate which is green in color
cuso4 +fe =feso4 +cu

Answer 2

Heya... Empress here Queen :)

So, with the help of an simple activity, I'm gonna show that Iron is more reactive than copper....
But first we must give the Equation for the experiment :-

AND THAT WILL BE

Fe + CuSO4 => FeSO4 + Cu

And for the experiment... I present u the procedure :-

1. Take an iron object, without the coating of rust as it may change the reaction. An iron nail will be good.

2. Take some of the CuSO4 solution and dip that nail into it.

3. So, after sometime you'll be observing that a colored layer starts to take over the iron nail.

And that shows, iron is more reactive than copper.
If copper were to be more reactive, then it would not have been taking over the iron. It should have been the same.
