Calcium chloride was apparently discovered in the 15th century but wasn't studied properly until the 18th century. [11] It was historically called "fixed sal ammoniac" (Latin: sal ammoniacum fixum [12]) because it was synthesized during the distillation of ammonium chloride with lime and was nonvolatile (while the former appeared to sublime); in more modern times (18th-19th cc.) it was called ...
Calcium chloride (CaCl 2) is a salt that is marketed in pellet form for removing dampness from rooms. Calcium chloride is also used for maintaining unpaved roads and for fortifying roadbases for new construction. In addition, calcium chloride is widely used as a de-icer, since it is effective in lowering the melting point when applied to ice. [23]

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 ...
Calcium is a chemical element; it has symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium.
Calcium hypochlorite is a general oxidizing agent and therefore finds some use in organic chemistry. [6] For instance the compound is used to cleave glycols, α-hydroxy carboxylic acids and keto acids to yield fragmented aldehydes or carboxylic acids. [7] Calcium hypochlorite can also be used in the haloform reaction to manufacture chloroform. [8]
Ringer's solution typically contains sodium chloride, potassium chloride, calcium chloride and sodium bicarbonate, with the last used to buffer the pH. Other additions can include chemical fuel sources for cells, including ATP and dextrose , as well as antibiotics and antifungals.
Calcium formate is separated from the solution, heat treated to remove formaldehyde and then dried. [5] Calcium formate can also be made from calcium hydroxide and carbon monoxide at high pressure and temperature [2] – e.g., at 180 °C and 35 atm. [10] It may also be made from calcium chloride and formic acid. [2]
