Caption: Copper (II) sulphate in hydrated (blue) and anhydrous (white) forms. This chemical compound varies in colour according to the amount of hydration. If no or little water is present (anhydrous), it is white or pale green. The pentahydrate form (with five molecules of water for each molecule of copper sulphate, CuSO4. 5H2O) is the bright blue seen here.
