The process of losing electrons is called "Oxidation" and the process of gaining electrons is called "Reduction". These two processes taking place simultaneously hence we call it as '''“Redox reaction”'''. Here, Iron loses electrons whereas Copper gains electrons. So, Iron is more reactive than Copper hence, it displaces Copper from Copper sulphate solution.

These two processes taking place simultaneously hence we call it as [http://www.chemguide.co.uk/inorganic/redox/definitions.html '''“Redox reaction”''']. Here, Iron loses electrons whereas Copper gains electrons. So, Iron is more reactive than Copper hence, it displaces Copper from Copper sulphate solution.
