So, is CaCl2 Ionic or Covalent? CaCl2 is an ionic compound owing to the large electronegativity difference between the calcium atom and chlorine atom, which is greater than 2.0. This reaction results in an appreciable increase in temperature i.e., exothermic reaction, and hence, dissolution of calcium chloride in water has a high enthalpy of solvation. CaCO3 + 2NaCl → CaCl2 + Na2CO3Ĭalcium chloride produces free calcium ions i.e., the aqua complex of calcium ion and chloride ion by dissolving themselves in water as follows Calcium chloride is prepared by reaction of calcium hydroxide with hydrogen chloride.Ĭalcium chloride can also be produced from limestone by the Solvay process i.e. Generally, calcium chloride is found in the hydrated form i.e., CaCl2 (H2O)n, where n = 0, 1, 2, 4, and 6. The molecular weight of its anhydrous form is 111 g/mol. However, the melting point of hexahydrate calcium chloride is only 29.9 ☌. The melting and boiling point of anhydrous calcium chloride is very high. It is hygroscopic in nature and hence, used in the desiccators for drying chemicals. ![]() ![]() It is an inorganic compound of white color without any odor.Ĭalcium chloride is crystalline in nature and can be easily dissolved in water. CaCl2, referred to as calcium chloride, is a member of alkaline earth metal halides i.e., MX2, where, M is an alkaline earth metal. ![]()
