It occurs naturally in various forms, which differ in their crystal water content: gypsum (CaSO 4 ·2H 2 O), the hemihydrate (CaSO 4 ·0.5H 2 O) also known as plaster of Paris, and the anhydrite. Besides the natural sources, calcium sulfate is also produced as a by-product, mainly from the desulfurization of exhaust gases of fossil-fuel power stations.

The study of thermodynamics crosses many disciplines, including physics, engineering, and chemistry. Of the various branches of thermodynamics, the most important to chemistry is the study of the change in energy during a chemical reaction.

For example, the complex of Ni(II) with three ethylenediamine ligands should be chemically similar to the Ni(II) complex with six ammonia ligands. In fact, the equilibrium constant for the formation of the ethylenediamine complex is almost 10 orders of magnitude
