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.
The metal calcium is an Alkaline Earth element, which is found in Group 2 of the periodic table. All the Group 2 elements have two valence electrons, and these elements want to loan them both out. This will leave a calcium ion with a +2 charge. Because calcium wants to loan out both its valence electrons, it will form compounds based on its desire to do so. Calcium will form bonds in a one-to-one ratio with elements that want to borrow 2 electrons, like oxygen.
