A negative change indicates the reaction is exothermic, while a positive value means it is endothermic. This tool calculates the change of the reaction in two ways: 1. Using the enthalpy equation, or 2. MgCl2 crystallizes in the cadmium chloride CdCl2 motif, which features octahedral Mg centers. Several hydrates are known with the formula MgCl2·nH2O, and each loses water upon heating: n = 12 (−16.4 °C), 8 (−3.4 °C), 6 (116.7 °C), 4 (181 °C), 2 (about 300 °C). In the hexahydrate, the Mg is also octahedral, but is coordinated to six water ligands. The thermal dehydration of the hydrates MgCl2·nH2O (n = 6, 12) does not occur straightforwardly.
