Thermodynamics of proton dissociations from aqueous citric acid: apparent molar volumes and apparent molar heat capacities of citric acid and its sodium salts at the pressure 0.35 MPa and at temperatures from 278.15 K to 393.15 K

Properties of Citric Acid and Its Solutions

“…However, this is not the case of much more sensitive C p,2,ϕ quantities. The most accurate sets of C p,2,ϕ, the apparent heat capacities of Patterson and Wooley [114] and Sijpkes et al [113] behave similarly as a function of concentration, but even they are shifted by about 10 J mol…”

“…As pointed above, Patterson and Woolley [114] performed measurements of density that cover a large temperature range, from 5 to 95 °C. Since they reported the apparent molar volumes at constant molalities, from 0.03 to 1.0 mol kg…”

“…This is illustrated in Fig. 2.33 where the specific heat capacities which were determined by Patterson and Wooley [114] are plotted.…”

Dissociation Equilibria in Solutions with Citrate Ions

“…The Patterson and Woolley [15] results for the heat capacity and enthalpy changes in dissociation reactions of citric acid can be correlated by …”

Volumetric Properties of Some Aliphatic Mono- and Dicarboxylic Acids in Water at 298.15 K

“…shows that only a few authors have attempted to determine values of the apparent molar volumes of carboxylic acids in water [5][6][7][8][9][10][11][12][13][14][15].…”
