In CuSO4 ,Cu is in the oxidation state of +2 which is converted to metallic state . Here Cu2+ gains 2 electrons. Gain of Electrons is Reduction. Fe loses 2 electrons to form Fe2+. Loss of Electrons is Oxidation. (LEO goer GER). Since simultaneous oxidation and reduction takes place it is a redox reaction.
