Thermodynamic data that have been obtained subsequent to compilations by the U.S. National Bureau of Standards and Latimer now permit calculation of ΔGf0, ΔHf0, and [Formula: see text] values for RuO42− (aq) and MoO42− (aq). Use of these quantities is illustrated by calculation of thermodynamic properties of Ag2MoO4 (c).

Equations in the form of Chebyshev polynomials are presented which enable the thermodynamic properties of saturated water in its liquid and vapour phases to be calculated in a systematic manner. In the equations defining the pressure-temperature relationship the authors have made allowance for certain unpublished observations of the National Bureau of Standards and these are considered in the section relating to vapour pressure. It is believed that the assembly of equations specify for the first time the saturated liquid and vapour boundaries whose properties have previously only been available in tabular form.

Modeling of the Thermodynamic Properties of Liquid Fe-Ni and Fe-Co Alloys From the Surface Tension DataRecently proposed method of modeling of thermodynamic properties of liquid binary alloys from their surface tension data is described. The method utilizes Melford and Hoar equation, relating surface tension with excess Gibbs free energy, combined with new description of the monatomic surface layer and β parameter. The method is tested on Fe-Ni and Fe-Co alloys and the obtained results show very good agreement with experimental thermodynamic data of other authors. The model allows also to calculate the surface tension from thermodynamic data, and it gives better agreement with experimental results than those modeled with the use of Butler equation and traditionally defined monatomic surface layer and β = 0.83.

Titanium Trichloride

The free-energy values for titanium trichloride were determined to within 0.5 kcal per mole, using a " null " method with mercury and silver as reductants. Attempts to obtain free-energy values by means of the hydrogen reduction of titanium tetrachloride vapour failed to give reliable results owing to reactions between the trichloride and the glass ampoule. Thermodynamic data for titanium dichloride were obtained by vacuum disproportionation of the trichloride.
