Application of Mckay and Perring equations to the activity coefficients of electrolytes in two aqueous non-electrolyte–electrolyte systems at 298.15 K Comparison with isopiestic measurements

Abstract

The activity coefficients of electrolytes for the aqueous non-electrolyte–electrolyte systems (water–mannitol–NaCl) and (water–mannitol–KCl) at 298.15 K have been calculated by the Mckay and Perring equation. The results are compared with experimental data obtained from isopiestic measurements. Agreement is in general excellent.
