Comments on “Thermodynamic Models for Correlation of Solubility of Hexaquocobalt(II) Bis(p-toluenesulfonate) in Liquid Mixtures of Water and Ethanol from 288.15 to 333.15 K”

Abstract

Mathematical representations reported by Yu et al. for the CNIBS/R-K model and a hybrid model are carefully examined in regards to the model's ability to predict the solubility of hexaquocobalt(II) bis(p-toluenesulfonate). The equation coefficients reported by Yu et al. were found to give calculated mole fraction solubilities in ethanol that exceed unity for both models.

“…The models are commonly used in the chemical and pharmaceutical industries. In the past two years there have been several incorrect applications ,− of the models that have led to calculated mole fraction solubilities that have exceeded unity in one or both of the monosolvents used to prepare the binary solvent mixture. Several of the incorrect applications ,, have involved solubility studies in which the authors performed experimental measurements in a very narrow range of binary solvent composition.…”
