Thermodynamics of aqueous mixed potassium carbonate, bicarbonate, and chloride solutions to 368 K

Potentials for the cell without liquid junction H/sub 2/,Pt vertical bar K/sub 2/CO/sub 3/(m/sub 1/),KHCO/sub 3/(m/sub 2/),KCl(m/sub 3/) vertical bar AgCl,Ag are reported over a wide range of ionic strengths at temperatures to 368.15 K. Analysis of these results with the ion interaction model shows...

Zusammenfassung:	Potentials for the cell without liquid junction H/sub 2/,Pt vertical bar K/sub 2/CO/sub 3/(m/sub 1/),KHCO/sub 3/(m/sub 2/),KCl(m/sub 3/) vertical bar AgCl,Ag are reported over a wide range of ionic strengths at temperatures to 368.15 K. Analysis of these results with the ion interaction model shows that only very minor changes in the previously reported temperature dependence of the potassium carbonate interaction parameters are required to represent the higher temperature data. Activity and osmotic coefficients for solutions with stoichiometrically equal carbonate and bicarbonate molalities are calculated from 338 to 368 K.
