Onsager Equation

The application of a modified form of the Onsager equation at the condition of infinite dilution of a polar solute in a polar solvent leads to reasonable dipole moments for water, pyridine, acetone, tert-butyl alcohol, n-butyl alcohol, and β-octyl alcohol, except in the case of water in tert-butyl alcohol at 30 and 40 °C and the case of acetone in n-butyl alcohol at 30 to 50 °C. The initial decrease of the dielectric constant of solvent by addition of solute in each of these two cases is associated with a reduction in the Kirkwood g-factor of solute. In all 12 systems investigated, strong hydrogen bonding occurs between solute and solvent molecules and often between solvent molecules themselves. It is thought that this equation must fail when short-range interactions assume predominant importance, but why it works so well for those cases which are also strongly interacting systems is not clear.

Coefficient Of Viscosity

We have measured the coefficient of viscosity B at 25 °C of HCl, LiCl, NaCl, KCl, RbCl, KI, and KBr in the mixtures of aqueous organic solvents containing from 10 to 40% tert-butyl alcohol by weight (X), the concentration of electrolyte varying from 0.1 to 0.3 M.Plots of B = f (x) show points of inflexion and minima whose positions can be explained by the structural properties of the mixed solvent.In water, a linear relationship between the entropy of hydration and coefficient B of the ions is observed. In the same way, it can be shown that a linear correlation exists between the entropy of solvation and coefficient B of the electrolytes for all the mixtures studied.These correlations lead to the characterization of two distinct zones (X < 20% and X > 20%) for the range of tert-butyl alcohol–water mixtures.
