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.
For example, in the reaction of calcium and chlorine, the compound is called calcium chloride. It is composed of Ca cations and Cl anions; those ions are stable since they have filled valence shells. Its ionic formula is written as CaCl2, the neutral combination of these ions. Two chloride ions were needed in the final compound because calcium had a 2+ charge. To create a neutral compound, CaCl2, two 1- chloride ions were needed to balance out the 2+ charge from calcium.
