Volumetric properties of aqueous sodium chloride solutions from 0/sup 0/ to 500/sup 0/C at pressures up to 2000 bars based on a regression of available data in the literature
The volumetric properties of aqueous sodium chloride solutions from 0/sup 0/ to 500/sup 0/C at pressures up to 2000 bars for concentrations ranging from infinite dilution to as high as 8.0 molal were obtained by a computer regression of the available experimental data from the literature. The regression was done using (1) the simplest forms of equations capable of describing the experimental data, (2) unsmoothed data where possible, and (3) a least-squares regression technique in which the individual data points were weighted with respect to their relative uncertainty. By following this procedure, a set of internally consistent data was generated. The results are presented in 27 tables of density data at various concentrations, temperatures, and pressures. Two tables of empirical constants capable of generating the tables of density values as well as interpolating the tabulated values are also given.
