Calcium chloride is a chemical compound made up of calcium ions and chlorine ions. The ions are held together by an ionic, or weak salt bond. Mixing calcium chloride with water is an exothermic reaction, which means that the combination of the two substances releases heat. Thus, when you ad...
A. Calcium carbonate and hydrochloric acid react to give calcium chloride, water and carbon dioxide. B. Calcium carbonate combines with hydrochloric acid to produce calcium chloride, water and carbon dioxide. C. Calcium carbonate plus hydrochloric acid makes calcium chloride, water and carbon dioxide...
Chemical Properties Calcium chloride, CaC12, is colorless deliquescent solid that is soluble in water and ethanol. It is formed from the reaction of calcium carbonate and hydrochloric acid or calcium hydroxide and ammonium chloride. It is used in medicine, as an antifreeze, and as a coagulant....
Calcium chloride is produced in commercial amounts using many different procedures. The main procedures are by refining natural brines, Solvay process, and reaction of hydrogen chloride with calcium carbonate. Calcium chloride consumption is very dependent on weather since its main use is in deicing,...
In Liebig’s process, chlorine is passed into milk of lime, at or above a temperature of 1000°C, the apparent reaction being: 6Ca(OH)2+ 6Cl2→5CaCl2+ Ca(CIO3)2+ 6H2O. But this may comprise two minor reactions: 2Ca (OH)2+ 2Cl2→CaCl2+ Ca(OCl)2+ 2H2O; 3Ca(OCI)2→2CaCl2...
It reacts violently with brominetrifluoride, and a reaction with zinc releases explosive hydrogen gas.It has an exothermic reaction with water, and when heated todecomposition it emits toxic fumes of chlorine. 4.3 WGK Germany 1 4.3 RTECS EV9810000 4.3 Report ?Calcium chloride (CAS NO.10043-52...
Contrary to magnesium placed directly above calcium in the periodic chart, elementary calcium reacts with water at room temperature, according to the following reaction mechanism: Ca (s) + 2H2O (g) -> Ca(OH)2(aq) + H2(g) This reaction forms calcium hydroxide that dissolves in water as ...

In particular, calcium chloride is usually used to pack “drying tubes” to exclude atmospheric moisture from a reaction setup while allowing gases to escape. It cannot, however, be used to dry alkaline gases such as ammonia because it will form addition products. It is used to dry kelp, ...
