Investigation of the Na2(H2PO2)2 - Ba(H2PO2)2 - H2O Water-Salt Ternary System at Room Temperature

Abstract

Objective: In this study, the solubility, density, conductivity and phase equilibria of the Na2(H2PO2)2-Ba(H2PO2)2-H2O ternary system located in the structure of the Na+, Ba2+, (H2PO2)-//H2O quaternary reciprocal water-salt system were investigated using physicochemical analysis methods. Material and Methods: Riedel-de Haen and Merck salts were used to investigate the solubility and phase equilibria of the Na2(H2PO2)2 -Ba(H2PO2)2-H2O ternary water–salt system at room temperature Results: It was determined that the Na2(H2PO2)2-Ba(H2PO2)2-H2O ternary water-salt system belongs to the simple eutonic system type and the compositions corresponding to the eutonic point, expressed as mass %, were 50.73, 0.53 and 48.74 (w/w %) for Na2(H2PO2)2, Ba(H2PO2)2 and H2O, respectively
