Activity coefficient— of solvent

Show how a measurement of the boiling point elevation may be used to determine the activity coefficients of solvent and of ionic species in solution. [Pg.400]

Equation (3D-5) can be applied to all pressures and temperatures, but for determining the activity coefficients of solvents in the liquid phase of a polymer solution Equation (3D-5) can be simplified by solving for the volume roots at zero pressure instead of the pressure of the system. [Pg.65]

The starting point for the derviation of the activity coefficient of solvent S in a solution with electrolyte AB is the Gibbs-Duhem equation. [Pg.478]

Electrostatic interactions give a large deviation from ideality in equilibrium properties of solutions containing low molecular weight electrolytes. This deviation was most successfully disposed of by the Debye-Huckel theory [2]. According to this theory, the ionic species are not distributed in solution in a random manner, but form an ionic atmosphere structure, and the thermodynamic properties such as the activity coefficient of solvent (or the osmotic coefficient), the mean activity coefficient of solute, and the heat of dilution, decrease linearly with the square root of the concentration, in conformity with experimental observations. [Pg.71]

Often r is approximated by the ratio of the molar volumes of pure liquid polymer and pure solvent. The segment fractions of solvent and polymer are then equal to the volume fractions of solvent and polymer, and p. Equation (27) is derived using many assumptions and approximations (for a discussion, see Ref. 8), but on the basis of this rather simple expression many features of the phase behavior of polymer solutions can be explained. The expressions for the mole fraction based activity coefficients of solvent and polymer are Eqs. (30) and (31), respectively. [Pg.22]
