CALCIUM CHLORIDE - WIKIPEDIA

Calcium chloride dissolves in water, producing chloride and the aquo complex [Ca(H2O)6] . In this way, these solutions are sources of "free" calcium and free chloride ions. This description is illustrated by the fact that these solutions react with phosphate sources to give a solid precipitate of calcium phosphate: 3 CaCl2 + 2 PO3−4 → Ca3(PO4)2 + 6 Cl
