Calcium chloride is a highly soluble calcium salt. Hexahydrate calcium chloride (CaCl 2 ·6H 2 O) has solubility in water of 811 g/L at 25 °C. [1] Calcium chloride when taken orally completely dissociates into calcium ions (Ca 2+) in the gastrointestinal tract, resulting in readily bioavailable calcium. The high concentration of calcium ions ...

Calcium hydroxychloride is sometimes confused with calcium hypochlorite. Calcium hydroxychloride is a double salt, which consists of calcium cations Ca 2+ and two kinds of anions, chloride Cl − and hydroxide − OH, while calcium hypochlorite consists of calcium cations Ca 2+ and only one kind of anions, hypochlorite − OCl.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Calcium hydroxide is modestly soluble in water, as seen for many dihydroxides. Its solubility increases from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. [8] Its solubility product K sp of 5.02 × 10 −6 at 25 °C, [1] its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction:
Antarcticite is an uncommon calcium chloride hexahydrate mineral with formula CaCl 2 ·6H 2 O. It forms colorless acicular trigonal crystals. It is hygroscopic and has a low relative density of 1.715.
The cobalt chloride mentioned above occurs as [Co(H 2 O) 6] 2+ and Cl −. In tin chloride, each Sn(II) center is pyramidal (mean O/Cl−Sn−O/Cl angle is 83°) being bound to two chloride ions and one water. The second water in the formula unit is hydrogen-bonded to the chloride and to the coordinated water molecule.
