Аннотация
Some of the parameters and equilibrium constants of quaternary salts solutions KBr–K2SO4–K2B4O7–H2O and NaBr–Na2SO4–Na2B4O7–H2O at 298 K are calculated using the correlation equation of the Pitzer parameters. The solubilities data of the ternary subsystems were fitted by multiple linear regression method. The phase diagram was plotted. A comparison between the calculated and experimental results for the systems shows that the predicted solubilities agree well with experimental data.
