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 ...
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...
5,5′-Bitetrazole 26 is a strong dibasic acid close in acidity to oxalic acid (see Table 17). From the values of pKa1 and pKa2 of 5,5′-bitetrazole 26 and other 5-substituted tetrazoles (Table 17), σ-constants for the tetrazole ring as a substituent were determined: for the NH-...
and venting gas. The gas samples were injected in vacuum glass tubes (vacutainer) and send to Beta Analytic laboratory in Florida, U.S.A. The modern reference standard was 95% the14C activity of the National Institute of Standards and Technology (NIST) Oxalic Acid (SRM 4990C) and calculated...

(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...
