The difference is that $\ce{CuSO4.5H2O}$ has a blue colour due to the presence of water molecules in its structure (for same reason ferrous sulphate has a green colour), while anhydrous copper (II) sulphate, $\ce{CuSO4}$, is white. A derogation of classification is proposed for copper (II) oxide and copper powder due to poor bioavailability, large particle size and low toxicity and for copper sulphate due to large particle size of the current products (d50 220 µm).
