摘要: Abstract This paper presents a new model to correlate osmotic and activity coefficients of electrolyte solutions. The contains long-range interactions term based upon Debye-Huckel theory (Debye- Huckel, DH or Pitzer-Debye-Huckel, PDH) short-range extended solvation (ST). Testing the correlative capability used 56 aqueous solutions: 1:1, 1:2, 1:3, 1:4, 2:1, 2:2, 3:1, 3:2 4:1 at 298.15 K. average percentage deviation, standard deviation its bias from experimental data are (0.48, 0.25 and −0.001) (0.69, 0.26 0.005) for DH-ST PDH-ST, respectively. results demonstrate that equation correlates effectively.
