摘要: Equations relating osmotic, mean ionic activity, and water activity coefficients to electrolyte concentrations in binary aqueous solutions were substantiated within the framework of cluster concepts. The model includes contribution solution nonideality electrostatic interactions terms Debye-Huckel theory along with hydration association salts via relations containing numbers standard states. According description data on 54 1-1 electrolytes, this should be given preference compared most extensively used NRTL, NRTL-NRF, Wilson, Pitzer models.
