Abstract

The solubility of calcium oxalate inonohydrate was determined via atomic absorption spectroscopy in a series of 1-alkanols and ethanol-water mixtures at 25°C., having known dielectric constants. It was found that solubility was linearly related to the dielectric constant of the 1-alkanols. In the ethanol-water mixtures, the solubility isotherm was curvilinear and on a dielectric constant basis an apparent break occurred in the isotherm, at a dielectric constant of sixty. This can be considered to be the point of ionization of divalent cations. The solubility isotherms in the cosolvent mixtures can be considered as repressive ionization phenomena.
