Solute and Solvent Activities of CaCl2(aq) Solutions from the Adsorption Isotherm Treatment

摘要: The values of the two Brunauer−Emmett−Teller (BET) parameters calculated by Stokes and Robinson (1948) are reevaluated using recent experimental data on activity coefficients CaCl2(aq) reported Rard Clegg (1997). At 95% confidence level, no significant statistical differences observed in BET this work those (1948). water activities aw, osmotic φ, mean ionic coefficients, γ± then from saturation to dilute solution. Since standard state solute model is anhydrous liquid electrolyte rather than infinitely solution, technique Ally Braunstein (1996) utilized obtain over entire concentration range. between chemical potentials solution (hypothetical) elect...
