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 [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.
