text: Depending on the change in Gibbs free energy (ΔG) of the dissolution reaction, i.e., on the endothermic (ΔG > 0) or exothermic (ΔG < 0) character of the dissolution reaction, the solubility of a given compound may increase or decrease with temperature.
text: Occasionally, a more complex pattern is observed, as with sodium sulfate, where the less soluble decahydrate crystal (mirabilite) loses water of crystallization at 32 °C to form a more soluble anhydrous phase (thenardite) because the change in Gibbs free energy (ΔG), of the dissolution reaction.[citation needed]
