چکیده

in this work we have applied the dense system equation of state (dseos) to electrolyte solutions. we have found that this equation of state can predict the density of electrolyte solutions very accurately. it has been tested for different electrolytes solutions at different temperatures and compositions. a hypothetical binary model has been applied to find the dependencies of parameters of this equation of state on solution temperature and composition. using such a simple model the heat capacity of nacl solution was calculated for which the absolute percent deviation is less than 2 %. the dseos is tested for the following electrolytes: na2so4, mgcl2, mgso4, kcl, nacl, and nabr. we found that the dseos predicts the density of aqueous electrolyte solutions mentioned above accurately so that its percent error in density is less than 0.04.

An Equation of State for Nonaqueous Electrolyte Solutions

A two parameters equation of state (EOS) for nonaqueous electrolyte solutions system has been developed. The equation is in terms of Helmholtz free energy and incorporated with results of low density expansion of non-primitive mean spherical approximation. The EOS was tested for experimental data reported in literatures of 9 nonaqueous single electrolyte solutions of which the temperature was 2...
