Caption: Copper (II) sulphate being heated in a test tube. In hydrated copper (II) sulphate (blue), water is held within its structure by hydration bonds. When it is heated, the hydration bonds are broken down and the water evaporates off, leaving behind de-hydrated (anhydrous) copper (II) sulphate (white). This reaction is endothermic (absorbs heat). For the reverse of this reaction see image A500/0824.
