Description

In experiment C4.3.1.1, copper(II) sulfate in the pentahydrate form and in the anhydrous form is used to demonstrate the principle of endothermic and exothermic reactions. Here the reaction of copper(II) sulfate-5-hydrate under high heat to anhydrous copper(II) sulfate represents the endothermic reaction. The anhydrous copper(II) sulfate obtained in this way reacts in turn with water while generating heat, thereby demonstrating an exothermic reaction.
