Calcium chloride can serve as a source of calcium ions in an aqueous solution, as calcium chloride is soluble in water. This property can be useful for displacing ions from solution.For example, phosphate is displaced from solution by calcium:aCl 2(l) â Ca (s) + Cl 2(g). Calcium chloride has a very high enthalpy change of solution. A considerable temperature rise accompanies its dissolution in water. The anhydrous salt is deliquescent; it can accumulate enough water in its crystal lattice to form a solution.
Calcium is classified chemically as one of the alkaline earth elements (that is, in Group 2 of the periodic table. The metal is rather reactive. It readily forms a white coating of calcium nitride (Ca3N2) in air. It reacts with water and the metal burns with a yellow-red flame, forming largely the nitride. 1  Name: calcium. 2  Symbol: Ca. 3  Atomic number: 20. 4  Relative atomic mass (Ar): 40.078 (4) [see note g] 5  Standard state: solid at 298 K. 6  Colour: silvery white. 7  Classification: Metallic.
