Abstract[edit]
The different hydrate stages of calcium chloride are presented, as well as their behavior regarding solubility and hygroscopicity.
Hydrate stages[edit]
Sinjarite: CaCl2•2H2O
Calcium chloride tetrahydrate: CaCl2•4H2O
Antarcticite: CaCl2•6H2O
Solubility[edit]
Under standard conditions the hexahydrate of calcium chloride Antarcticite is the stable form. The salt has got a high solubility in water which increases with increasing temperatures. The dehydration steps to the calcium chloride tetrahydrate and to sinjarite take place at temperatures of 30 °C and 45 °C, respectively.
Hygroscopicity[edit]
