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....

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...

Anhydrous calcium chloride can be prepared by the following two main methods: 1. Calcium chloride is generated by the reaction of sodium chloride and calcium hydroxide, and the water is removed by dehydration treatment to obtain anhydrous calcium chloride; ...
Method: natural anhydrite is derived by the reaction of CaO with SO3 under red-hot. Soluble anhydrous gypsum is derived by CaSO4·2H2O which heated at 200℃ to constant. Hemihydrate gypsum is derived by the calcination dehydration. Dihydrate is reacted by calcium chloride and ammonium sulfate....
