Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl 2 ·nH 2 O, where n = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust control. Because the anhydrous salt is hygroscopic and deliquescent, it is used as a desiccant. [10]
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.
Calcium compounds were known for millennia, though their chemical makeup was not understood until the 17th century. [34] Lime as a building material [35] and as plaster for statues was used as far back as around 7000 BC. [36] The first dated lime kiln dates back to 2500 BC and was found in Khafajah, Mesopotamia.

Calcium hypochlorite is an inorganic compound with chemical formula Ca(Cl O) 2, also written as Ca(OCl) 2.It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air.
Calcium iodide (chemical formula CaI 2) is the ionic compound of calcium and iodine. This colourless deliquescent solid is a salt that is highly soluble in water. Its properties are similar to those for related salts, such as calcium chloride. It is used in photography. [1] It is also used in cat food as a source of iodine.
When concentrated solutions of calcium chlorate and potassium chloride are combined, potassium chlorate precipitates: [1] [2]. Ca(ClO 3) 2 + 2 KCl → 2 KClO 3 + CaCl 2. This is the second step of the Liebig process for the manufacture of potassium chlorate.
Calcium(I) chloride (CaCl) is a diatomic molecule observed in certain gases. [ 1 ] A solid with the composition CaCl was reported in 1953; [ 2 ] however, later efforts to reproduce this work failed. [ 3 ]
