Abstract

The different hydrate stages of calcium chloride are presented, as well as their behavior regarding solubility and hygroscopicity.

Hydrate stages

Sinjarite: CaCl₂•2H₂O
Calcium chloride tetrahydrate: CaCl₂•4H₂O
Antarcticite: CaCl₂•6H₂O

Solubility

Figure 1: Solubility of calcium chloride in water. The molality m [n(CaCl₂•xH₂O)•kg(H₂O)^-1] is plotted against the temperature.

Hygroscopicity

Figure 2: Deliquescence behaviour of calcium chloride in the temperature range from -45 to 80 °C. The water activity a_w is plotted against the temperature.

concentration given as amount of substance (mol) of the dissolved substance per kilogram solvent; unit: mol•kg-1.
