Interaction in the Li2Mo3O10-CO(NH2)2-H2O system at 25°C

The solubilities and solid phases in the Li₂Mo₃O₁₀-CO(NH₂)₂-H₂O system at 25°C are studied. A compound of composition Li₂Mo₃O₁₀ · 6CO(NH₂)₂ · 4H₂O and lithium trimolybdate decahydrate Li₂Mo₃O₁₀ · 10H₂O are found to exist. The Li₂Mo₃O₁₀ · 6CO(NH₂)₂ · 4H₂O ray crosses the solubility isotherm, which indicates the congruent solubility of the double compound in water. The density, refractive index, dynamic viscosity, surface tension, electrical conductivity, and pH of saturated solutions of the system are determined. The molar volume, equivalent electrical conductivity, reduced conductivity, and solution ionic strength isotherms are calculated. A strong correlation between all the property isotherms and the solubility is observed.
