Abstract:Pitzer parameters of the single electrolyte in the system Na+,K+,Mg2+∥NO3-,Cl-,SO42——H2O at 298.15K have been obtained and discussed which can be used to describe thermodynamic properties and to predicate solubilities of the system in the previous papers.Pitzer mixing parameters for the quaternary system K+,Mg2+∥NO3-,SO42——H2O at 298.15K and their applications are given in this paper as one of a series of the research work.
Keywords:Thermodynamics  Solubility  Pitzer parameter
