Abstract

Abstract The solubilities of some univalent potassium salts (KF, KCl, KBr, KI, KClO₄, KSCN, and KCNO) in propylene carbonate (PC) were determined at different temperatures from (25.0 to 45.0) °C through flame emission spectroscopy. From the solubility measurements, the thermodynamic parameters ΔG ⁰, ΔH ⁰ and ΔS ⁰ of solution were calculated. Measurements were carried out via electrical conductimetry and FTIR to investigate the formation of ion pairs and the ion-solvent interactions. This study was motivated by the open question of whether specific ion (Hofmeister) effects are related to the structure of the solvent (i.e., hydrogen bonding). As for water, these effects are due to solute-induced solvent structure changes not accounted for by electrostatic forces.
