Comparison of different methods for calculation of the stoichiometric dissociation constant of acetic acid from results of potentiometric titrations at 298.15 K in aqueous sodium or potassium chloride solutions

Determination of Stoichiometric Dissociation Constants of Glycolic Acid in Dilute Aqueous Sodium or Potassium Chloride Solutions at 298.15 K

“…In this study, we continue the studies [1][2][3][4][5][6][7][8][9][10][11] dealing with the thermodynamics of weak acid solutions. The purpose of these studies is to determine the stoichiometric dissociation constants (for example the molality scale dissociation constants, K m ) for solutions of different weak acids as reliably as possible from potentiometric titration data and, additionally, from literature data obtained by galvanic cells without liquid junctions.…”

“…The difference between the observed and predicted electromotive forces, e E in Eq (22),. (4),(11) and(12)using the thermodynamic dissociation constant of 1.47 · 10 −4 , the recommended activity parameters and the glass electrode parameter E 0 shown in Tables 1 and 2. The predicted emf was calculated by Eqs.…”

Simultaneous determination of enthalpies of dilution and dissociation of protocatechuic acid in aqueous salt solutions by calorimetric measurements

“…B i is a parameter that is dependent on ion i, and b i, MCl is another parameter that is dependent on both ion i and the salt MCl present in the system. In the research work of Partanen [37][38][39][40], the following parameters have been determined for equation (7):…”

Sorption of Ampholytes in Weakly Acidic Ion Exchangers: Effect of Resin Ionic Form on Betaine Uptake

“…The parameters of the zwitterionic form were estimated from the osmotic and activity coefficient data of Smith and Smith [23] and Hong et al [24] The parameters for AcOH, HCl and NaCl were taken from Partanen and Juusola. [17] Solution densities needed in conversion between molar and molal concentrations were taken to be equal to the density of the background electrolyte solutions. Methods used in solution of algebraic equations and in parameter estimation were as in Laatikainen et al [19] EXPERIMENTAL The gel-type weak cation exchanger CA16G, obtained from Finex Oy (Finland), is composed of polyacrylic acid cross-linked with 8 wt% of divinylbenzene (DVB) and had an average particle diameter of 0.29 mm.…”
