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 sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant . One particular hydrate is better known as plaster of Paris , and another occurs naturally as the mineral gypsum .
Road salt can infiltrate surface and ground water, elevating sodium and chloride levels in drinking water reservoirs and wells; one teaspoon of road salt can permanently pollute five gallons of water. [19] Elevated sodium levels pose health risks for individuals with hypertension, and high chloride concentrations are toxic to aquatic life.
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.

Vinyl chloride was slowly released into the air Monday from five of those cars before crews ignited it to get rid of the highly flammable, toxic chemicals in a controlled environment, creating a ...
Calcium arsenate is commonly prepared from disodium hydrogen arsenate and calcium chloride: 2 Na 2 H[AsO 4] + 3 CaCl 2 → 4 NaCl + Ca 3 [AsO 4] 2 + 2 HCl. In the 1920s, it was made in large vats by mixing calcium oxide and arsenic oxide. [6] In the United States, 1360 metric tons were produced in 1919, 4540 in 1920, and 7270 in 1922. [1]
