The phase diagram of ternary system Na+ , Fe2+ /Cl -H2 O was established over the temperature range 0–70C by conductimetric and analytical methods. A solubility polytherm of the system was constructed. For each temperature, we have determined the nature of the solid phase in equilibrium with the solution and the limit of its area of existence.
