TL;DR: In this article, the initial temperature coefficients were measured for a thermogalvanic cell composed of two silver chloride electrodes in water-methanol solutions (WMS) of hydrogen chlorite at 298 K.
Abstract: The initial temperature coefficients are measured for the voltage of a thermogalvanic cell composed of two silver chloride electrodes in water-methanol solutions (WMS) of hydrogen chlorite at 298 K. The experimental results and earlier studies of thermoelectric properties of WMS of alkali metal halides are used to determine the entropy and partial molar entropy of the hydrogen ion moving in solution, the entropy change during its solvation, and the entropy carried by the hydrogen ion and a stoichiometric mixture of H+ and Cl- ions in various WMS. The influence of composition of a mixed solvent on the entropy characteristics of the hydrogen ion is analyzed.
TL;DR: In this paper, the integral heat of cyclohexanol (up to 0.10 mol kg −1 ) in benzene solutions of tri-n-octylammonium bromide was measured at 298.15 K.
TL;DR: In this paper, the enthalpies of dissolution of oxymatrine in 0.9% NaCl solution were measured using a RD496-2000 Calvet Microcalorimeter at 309.65 K under atmospheric pressure.
Abstract: The enthalpies of dissolution of oxymatrine in 0.9%NaCl solution were measured using a RD496-2000 Calvet Microcalorimeter at 309.65 K under atmospheric pressure. The differential enthalpy and molar enthalpy of oxymatrine dissolution in the 0.9%NaCl solution of were determined. The corresponding kinetic equation that described the dissolution process was elucidated. Moreover, the half-life, molar entropy, molar enthaply, and Gibbs free energy of the dissolution process were also obtained.
