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(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] Molecules of CaCl have been observed in the atmospheres of carbon stars. [4]
The Calcium-Dependent Chloride Channel (Ca-ClC) proteins (or calcium-activated chloride channels (CaCCs), [2] are heterogeneous groups of ligand-gated ion channels for chloride that have been identified in many epithelial and endothelial cell types as well as in smooth muscle cells.

Caution should be exercised when handling calcium chloride as it has the potential to release heat energy upon dissolution in water. This release of heat can lead to trauma and burns in the mouth, throat, esophagus, and stomach. In fact, there have been reported cases of stomach necrosis resulting from burns caused by calcium chloride. [46] [47 ...
By 1910, 270 permanent theatres operated in the country, including large capacity film palaces like the Royal Apollo. Film distribution was organized by the end of the decade. The first company to lend the film-shooting apparatus was the Projectograph, founded by Mór Ungerleider in 1908. The company also shot films, offering documentaries and ...
Chlorocalcite is a rare potassium calcium chloride evaporite mineral with formula: KCaCl 3. It is found in active volcanic fumaroles . It was first described in 1872 for an occurrence on Mount Vesuvius and given the name for its calcium content previous to discovering that it also contained potassium.
The original company was formed as a partnership in 1873 by John Brunner and Ludwig Mond.They built Winnington Works in Northwich, Cheshire and produced their first soda ash in 1874.
