Soluble calcium chloride chemical equation can be used to deploy a number of water-insoluble precipitate of calcium compounds: 3 CaCl2 (aq) + 2 K3PO4 (aq) → Ca3 (PO4) 2 (s) + 6 KCl (aq) calcium chloride After the electrolysis can be drawn pure calcium: CaCl2 → Ca (s) + Cl2 (g) [4] as it is easy to absorb moisture in the air occurs deliquescence of calcium chloride dihydrate, anhydrous calcium chloride must therefore be stored in sealed containers .
