Thermodynamic properties of tetra-alkylammonium ions in aqueous solution

摘要: The heat capacities of tetraethyl- and tetrapropyl-ammonium iodide have been measured in the temperature range 12–310 K. solubilities two salts determined at 298·15 auxiliary data used to calculate values 210 ± 3, 283 4, 336 5 J K–1 mol–1 for respective standard partial molar entropies ions NMe4+(aq), NEt4+(aq), NPr4+(aq), value aqueous proton being taken as zero. Equations designed reproduce hydration energies alkali alkaline-earth metal are unsuitable tetra-alkylammonium ions.
