Definition and Usage Areas of Calcium chloride

Calcium chloride and production, water-soluble aquo complex [Ca(lH 2 O) 6 ] 2+ . In this way, these solutions are sources of “free” calcium and free chloride ions. This explanation is illustrated by the way these solutions react with phosphate sources to give calcium phosphate a solid precipitate:

3 CaC 2 + 2 PO 3-
4 Ca → 3 (PO 4) 2 + 6 Cl –

Calcium chloride exhibits a very high enthalpy change, indicated by a significant temperature rise with dissolution of the anhydrous salt in water. This property forms the basis of its largest-scale application.

Molten calcium chloride can be electrolyzed to give calcium metal and chlorine gas.

CaC 2 , Ca + Cl → 2

Usage areas

• As a dust catcher in constructions as it is desiccant.
• As an additive in the plastics industry
• As an additive in fire dusts
• Melting the ice on the roads (does not harm the environment like normal salt)
• Concrete/Cement: It provides durability and strength to the concrete by drying the concrete quickly, especially in cold weather.
• In treatment: In reducing the high fluorine level in drinking water. Also, in the treatment of waste water from industrial facilities such as oil refineries and aluminum factories.
• Oil Exploration/Drilling: It is used extensively.
• In sports drinks
• Canned food (especially pickles)
• In some chocolate products
• In milk, cheese (as a calcium supplement)
• In brewing (as enzyme)
• In ice cream: As a freezer
• In Animal Feed: In dairy cattle, reducing milk fever and preventing disease
• Giving calcium to plants
• Reducing the sodium level in the soil
• Extending the shelf life of fruits and vegetables at harvest time
