Calcium Chloride, Formula, Chemical Properties, Preparation, Uses

Calcium Chloride

Calcium chloride is the chemical inorganic compound and contains the typical iconic halides that can be highly soluble in water. It can be obtained from the brine. It is the most abundant mineral and highly content the ancient seabeds. These calcium metal contributes the 25.5% elemental. The anhydrous is the most priority metal to produce the calcium chloride. The systematic IUPAC name is known as calcium chloride. The chemical or molecular name of calcium chloride is CaCl2.

Structural Formula

This is the structural formula of the calcium chloride:

Calcium Chloride

Chemical Formula

The chemical formula of the calcium chloride is CaCl2. It has consists of one calcium and two chloride ions.


By using the solvay process the calcium chloride is produced by treating the solution of sodium chloride and calcium carbonate. It crystallizes the calcium chloride at the high temperatures upto 1935oC. By heating the chloride salt it can produced the anhydrous with the hexamine complex to coordinate with the six water ligands. It is obtained from the purifaction of brine at room temperatures. These can also electrolysed and give the calcium with the chlorine gas.
