“…This and the very large decrease of static permittivity is in accord with the destruction by the electrolyte of the linear molecular associates of the pure solvent (3,33). The relaxation time of formamide, a solvent with H-bonded network similar to water, decreases on addition of Nal (11), but increases with LiNO3 (33).…”

“…Details of this (b) equipment are given in refs. (3,36) based on the 'know-how' acquired with preceding apparatus (31)(32)(33)(34). Purification of solvents, preparation of solutions, and measurements are carried out under a positive pressure of solvent saturated nitrogen gas such that the solutions are screened against evaporation and are never exposed to the atmosphere (3,4,36).…”

-High frequency permittivity of non-aqueous electrolyte solutions and their solvents is discussed in the framework of time domain and frequency domain methods. Evaluation of data is performed on the basis of models presupposing one or more relaxation processes. Depression of the solvent permittivity, relaxation times of the solvent molecules, and dispersion amplitudes and relaxation times of ion-pair relaxation are investigated with regard to actual theories underlying these phenomena. Information is obtained on structural and dynamical properties of classes of electrolyte solutions based on rotic H-bonding, dipolar aprotic, and low permittivity solvents and mixtures of solvents.

Starting from the most general form of the balance equation of thermal performance for thermometric and enthalpimetric methods of titration, the possibilities of these methods in analytical chemistry and in the field of determining data on materials are demonstrated and critically appreciated. The demand for reliable data on materials opens new fields of application of thermometric and enthalpimetric titration methods in the sphere of the thermal chemistry of solutions.

Articles you may be interested inAutodetachment spectroscopy and dynamics of dipole bound states of negative ions: 2 A 1-2 B 1 transitions of H2CCC− A new concept of ion association in electrolyte solutions is presented in this paper. The starting point for our theory is the activity expansion of osmotic pressure in the physical picture and the energetic definition of bound states in the phase space of ions. The weight function describing the contributions of the bound states to the second cluster coefficients is calculated. It is established that ion screening has a substantial influence on the formation of bound states. The equation of state is written in the chemical picture by splitting the two-particle screened cluster coefficient into bound and free parts. We show that the bound part of the cluster coefficient in the physical picture can be identified with the association constant in the chemical picture. The mass action law is derived in a self-consistent way.
