Mole map

Abstract: The densities of an ideal and a non-ideal liquid-liquid solution were determined experimentally. The experimental results were then compared to calculated values using two mathematical expressions for density, employing partial densities in one and mole fraction in the other. Results were presented in form of tables and graphs, indicating the validity of applying mole fractions in the estimation of liquid-liquid solutions. Key words: Density, ideal solution, non-ideal solution, mole fraction.

Abstract: For a binary mixture the V,x-diagram with isotherm and isobaric curves contains the complete information about the phase behavior of the system. In ternary mixtures isotherm and isobaric surfaces and additional information on the tie lines describe the complete phase behavior. For a binary mixture the V,x-phase diagrams corresponding to the classified P,T-phase diagrams are shown. The constitute binary V,x-phase diagrams and partly the critical V,x-surfaces of the ternary systems are shown for NH3-Xe-Ar and NH3-C2H4-CH4.
