Structure related fluctuation of refractive indices of aqueous strong electrolyte solutions.

■ The Structure of Aqueous Electrolyte Solutions

This review compares results of neutron and X-ray diffraction experiments with computer simu­ lation and theoretical calculation for aqueous electrolyte solutions at the atomic level in terms of the partial radial distribution functions of several ionic solutions, and includes results for the ion-water and ion-ion structure of systems containing alkali ions, alkaline earth ions, transition meta...

An Evaluation of Four Electrolyte Models for the Prediction of Thermodynamic Properties of Aqueous Electrolyte Solutions

In this work, the performance of four electrolyte models for prediction the osmotic and activity coefficients of different aqueous salt solutions at 298 K, atmospheric pressure and in a wide range of concentrations are evaluated. In two of these models, (electrolyte Non-Random Two-Liquid e-NRTL and Mean Spherical Approximation-Non-Random Two-Liquid MSA-NRTL), association between ions of opposit...

Modeling of Refractive Indices for Binary Aqueous Solutions of Some Alkane Polyols at Constant Temperature and Pressure

In this research, a theoretical study has been undertaken on the density and also on the relationship between refractive index and density for aqueous solutions. A simple linear equation is suggested to show this relationship. Also, a semi-empirical equation has been developed for estimating the constant of this linear equation. By using our suggested equations, the refractive indices of aq...

Density and refractive indices of lactose solutions.

Lactose, the disacch arid e commonly known as milk sugar , has for many years been of commercial impor tance. U nt il r ecently i ts principal usc was in the manufacture of pharmaceu ticals, food products, and in th e preparation of modifi ed di ets; however, the penicillium industry now also r equires large quantiti es of this sugar. ! In th e presen t investigation measurements h ave been mad...
