Hydrated oxalic acidClustersDissociationThe 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 ...
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 observ...
1c, d). The flares are, therefore, located between the BSR outcrop at 515–520 m and the edge of GHSZ at 550–585 m calculated using water column temperature measurements obtained locally in the pockmark field (Figs. 2b and 4; Supplementary Data 1) and the equilibrium equation for...
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 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 ...
