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 hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water. Generally the commercial substances are sold with a purity of 65% to 73% with other chemicals present, such as calcium chloride and calcium carbonate, resulting from the manufacturing process.

Calcium supplements may contribute to the development of kidney stones. [1] Acute calcium poisoning is rare, and difficult to achieve without administering calcium intravenously. For example, the oral median lethal dose (LD 50) for rats for calcium carbonate and calcium chloride are 6.45 [22] and 1.4 g/kg, [23] respectively.
Calcium hydroxychloride is sometimes confused with calcium hypochlorite. Calcium hydroxychloride is a double salt, which consists of calcium cations Ca 2+ and two kinds of anions, chloride Cl − and hydroxide − OH, while calcium hypochlorite consists of calcium cations Ca 2+ and only one kind of anions, hypochlorite − OCl.
