摘要

在 298.15 K 的整个混合溶剂成分范围内研究了卤化铵溶液在 N-甲基吡咯烷酮（MP）-水混合物中的密度，并计算了电解质的标准分摩尔体积。确定了混合物中铵离子的标准分摩尔体积。计算了电致伸缩、特定离子与溶剂的相互作用以及溶液结构变化对 \(\bar {V}_{i}^{0}\) 的贡献。结合混合溶剂的结构讨论了所得数值对混合物组成的依赖性。

Volume Properties of Ammonium Halide Solutions in an N-Methyl Pyrrolidone–Water Mixed Solvent at 298.15 K

The densities of solutions of ammonium halides in N-methylpyrrolidone (MP)–water mixtures were studied over the entire range of compositions of the mixed solvent at 298.15 K. The standard partial molar volumes \(\bar {V}_{2}^{0}\) of the electrolytes were calculated. The standard partial molar volume of the ammonium ion \(\bar {V}_{i}^{0}\) in the mixtures was determined. The contributions to \(\bar {V}_{i}^{0}\) due to electrostriction, specific ion–solvent interactions, and structural changes in solution were calculated. The dependence of the obtained values on the composition of the mixture is discussed in connection with the structure of the mixed solvent.
