Calcium chloride

Properties. Calcium chloride can serve as a source of calcium ions in a solution as calcium chloride is soluble. This property can be useful for displacing ions from solution. For example, phosphate is displaced from solution by calcium: 3 CaCl 2 (aq) + 2 K 3 PO 4 (aq) → Ca 3 (PO 4) 2 (s) + 6 KCl (aq). Molten calcium chloride can be electrolysed to give calcium metal and chlorine gas:
