The precipitation process of solid phases Mg 3 (OH) 5 CI‐4H 2 O (phase 5), Mg 2 (OH) 3 CI‐4H 2 O (phase 3), and Mg(OH) 2 was followed by the addition of NaOH water solution in MgCl 2 water solutions of different concentrations (0.001 to 4.8 mol dm −3 ) and characterized by chemical, potentiometric, coulometric, and X‐ray diffraction analyses. The concentration range in which the precipitation of solid phases occurs was determined. The phase distributions relative to the pH of solution and concentrations of magnesium and chloride were defined by the equilibrium diagram. The approximate solubility products of stable solid phases formed at different ionic strengths and at 293 K were determined.
