The ionic dissociation of the oxalic acid in water was examined by performing a theoretical study of the different properties of clusters formed by the acid with up to five water molecules. Geometry optimization and frequency calculations were done at density functional theory level with the B3LYP ...
TiO 2 enhanced the conductance of solutions of oxalic and phosphoric acid in anhydrous alcohol and in alcohol-rich mixed solvents. In water-rich mixed solvents "normal" behavior was ...
The solvent effects on the dissociation of the simplest dibasic organic acid were examined from the determi nation or the first and second dissociation constants of oxalic acid conductometrically and pH-metrically In water + 2-propanol mixtures (0-87 wt% of 2-propanol). The solubility values of...
The modern reference standard was 95% the 14C activity of the National Institute of Standards and Technology (NIST) Oxalic Acid (SRM 4990C) and calculated using the Libby carbon half-life (5568 years).Data availability All relevant data are included in the Supplementary material to this article...

Chapter 3 is dedicated to comprehensive presentation of mathematical procedures associated with dissociation of citric acid in water and in electrolyte solutions. Available in the literature dissociation constants are tabulated and their accuracy examine
The dependence of the dissociation constants of oxalic acid on temperature and composition of ethylene glycol-water binary mixtures have been studied. Thermodynamic and extrathermodynamic analysis of the obtained results have been examined. The pK values have been correlated with the dielectric constant ...
(including the "partial" degrees of dissociation in the second steps) and the concentrations of ionized and nonionized forms in dilute (0.1–10 mM) solutions are calculated for eight homologues of oxalic acids, namely, malonic, succinic, glutaric, adipic, pimelic, suberic, azelaic, and sebacic...
