Iron is more reactive than copper. Write activity to show this.

Activity to show that iron is more reactive than copper:

i. Take an iron nail.


ii. Take a beaker and make a copper sulphate (white crystals) solution in it.


iii. Now dip the iron nail in the copper sulphate.


iv. Leave the dipped iron nail in the solution for a few minutes.


We will observe that the copper sulphate solution which is blue becomes green in colour. This means iron has displaced copper from its sulphate and formed a new compound, i.e., ferrous sulphate which is green in colour.
