The name for CaCl2 is calcium chloride. CaCl2 = Calcium and Chlorine = Calcium Chloride. It is an ionic compound consisting of the calcium cation (Ca2+) and two chlorine anions (Cl–). The bivalent calcium metal forms an ionic bond with two chlorine atoms.
Calcium chloride is mainly produced by reacting limestone (CaCO3) with hydrochloric acid (HCl).
CaCO3 + 2 HCl → CaCl2 + CO2 + H2O
