Physical Properties of Calcium Chloride and Hydrates. Various physical properties of calcium chloride and its hydrates are listed in Table 1. Note that anhydrous calcium chloride and the lower hydrates release a large amount of heat when dissolved in water (negative values for Heat of Solution).
1 Ιουλ 1994 · A variety of experimental measurements for CaCl2 (aq) in the range from 5 mol.kg-1 to saturation at temperatures from 323 to 523 K, including the vapor pressures of the saturated solutions, are...
Molecular Formula: CaCl2 Molecular Weight: 111.0 CAS Number: 10043-52-4. This product is designated as ACS Reagent grade and meets the specifications of the American Chemical Society (ACS) for reagent chemicals. Calcium chloride is a commonly used reagent in biochemistry.
It can exist as a white powder in its anhydrous form or as white to colorless crystals when hydrated. In terms of its chemical properties, calcium chloride is highly soluble in water and releases a significant amount of heat upon dissolution.
Anhydrous calcium chloride, used for this purpose, can provide a measure of the moisture present in concrete. Aqueous calcium chloride (in solution with water) lowers the freezing point as low as −52 °C (−62 °F), making it ideal for filling agricultural implement tires as a liquid ballast, aiding traction in cold climates.
Anhydrous Calcium Chloride. BRINERS CHOICE anhydrous calcium chloride meets or exceeds the Food Chemicals Codex (FCC IV) monograph for aqueous solutions of calcium chloride, is manufactured according to the FDA Good Manufacturing Practice Guidelines, meets American Water Works Association (AWWA) standard B-550, and is Kosher certified.
Calcium chloride has an exothermic heat of solution. Solid products release a large amount of heat when dissolved in water. Chlorides in the presence of water and oxygen are associated with the accelerated corrosion of common metals, such as steel, copper and brass. Calcium chloride brines are electrically conductive.
