Abstract

The solubility and the physicochemical properties (density and conductivity) in the Na-Ba-Cl-H2O, Na-Ba-H2PO2-H2O, Na-Cl-H2PO2-H2O, and Ba-Cl-H2PO2-H2O ternaries, and in Na+, Ba2+/Cl-, (H2PO2)(-)//H2O reciprocal quaternary systems at 0 degrees C were investigated using the isothermal method. Two invariant point were determined in Na+, Ba2+/Cl-, (H2PO2)(-)//H2O reciprocal quaternary system. The composition of invariant point of the first (as a weight) was determined as fallowing; 15.03% mass NaCl, 12.36% mass BaCl2, 2.86% mass Ba(H2PO2)(2), and 69.75% mass H2O. It was plotted that the liquid phase and the following three solid phases were in equilibrium at the invariant point at 0 degrees C. These are NaCl, BaCl2 center dot H2O, Ba(H2PO2)(2)center dot H2O.
