Abstract

Standard e.m.f.s of the cells H2|HX|AgX–Ag (X = Cl, Br, or I) in 10, 60, 70, and 80%(w/w) dimethyl sulphoxide–water mixtures are reported. These, together with values for mixtures of other compositions determined earlier, were used to calculate the molar free energies of transfer of the halogen acids from water to the mixed solvents. Single-ion values were derived therefrom by use of the extrathermodynamic assumptions of Feakins et al. and discussed in terms of ion solvation. It is shown that the solvophilicity of the ions is largely determined by their acid–base' interactions with the solvent molecules. The structural features of the solvents are briefly discussed.

银-卤化银电极的标准电位和离子溶剂化在二甲基亚砜-水混合物中的25°C
报道了电池H2|HX| AgX-Ag (X = Cl, Br,或I)在10、60、70和80%(w/w)二甲亚砜-水混合物中的标准电磁脉冲。这些值,连同先前测定的其他成分的混合物的值,被用来计算卤素酸从水到混合溶剂转移的摩尔自由能。单离子值是通过Feakins等人的超热力学假设推导出来的,并在离子溶剂化方面进行了讨论。结果表明,离子的亲溶剂性在很大程度上取决于它们与溶剂分子的酸碱相互作用。简要讨论了溶剂的结构特点。
