A displacement reaction takes place. Iron being a more reactive element than copper displaces copper from its compound. Ferrous Sulphate which is green in color and copper a reddish brown element are formed.So, blue color of copper sulphate fades away and the solution becomes light green. displacement reaction takes place.
