16 Μαΐ 2017 · What goes around: The dissociation of a calcium-chloride ion pair in water (see Figure) involves rearrangements of the solvation shell of both ions. Using molecular simulations, we show that the coordination number of calcium by water molecules should be considered in addition to the interionic distance to investigate this process, in ...
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl 2. It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
Figure 1: Solubility of calcium chloride in water. The molality m [n (CaCl 2 •xH 2 O)•kg (H 2 O) -1] is plotted against the temperature. Under standard conditions the hexahydrate of calcium chloride Antarcticite is the stable form.

These conditions are defined by the phase diagram of the calcium chloride-water system shown in Figure 1. This figure can be used to determine which phases are expected under different temperature and concentration conditions.
28 Σεπ 2020 · The answer for solid calcium chloride apparently includes a lattice dissociation enthalpy of +2,258 kJ/mol. Here is an example of a supporting report (also found in Concise Encyclopedia of Chemistry by DeGruyter): Thus, when you add calcium chloride to water, the solution heats.
1 Ιαν 2023 · A new thermodynamic model has been developed in the framework of the combined HKF-Pitzer equations in order to describe solution properties and phase diagrams of aqueous chloride systems bearing calcium, up to elevated temperatures.
