An Investigation of the Solubility and Changes in Physicochemical Properties of NaCl+NaH2PO2+H2O Ternary System at 333 K

Solid-liquid equilibria and physicochemical properties of NaCl+NaH2PO2+H2O ternary system were investigated using isothermal method at 333 K. Solid phase compositions were obtained via Schreinemaker method. NaCl+NaH2PO2+H2O ternary system is simple eutectic type. One eutectic point, two invariant curves and two crystallization areas were seen in phase diagram. NaCl and NaH2PO2.H2O salts were determined in solid phase. It has been observed that NaH2PO2 has salting-out effect on NaCl in NaCl+NaH2PO2+H2O ternary system
