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]
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 ...

Calcium chloride treatment is generally used for the transformation of E. coli and other bacteria. [11] It enhances plasmid DNA incorporation by the bacterial cell, promoting genetic transformation. Plasmid DNA can attach to LPS by being added to the cell solution together with CaCl 2. [12]
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.
Calciothermic reactions are metallothermic reduction reactions (more generally, thermic chemical reactions) which use calcium metal as the reducing agent at high temperature. Calcium is one of the most potent reducing agents available, usually drawn as the strongest oxidic reductant in Ellingham diagrams , though the lanthanides best it in this ...
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.
