The paper explores solvation behavior of nicotinium, pyridinium, quinolinium dichromates at 288–318 K in acetone, water and varying compositions of water–acetone (v/v). Analysis of conductance data to obtain λ⁰ is on the lines of Kraus–Bray and Shedlovsky models. λ⁰, the limiting molar conductance, increased with increase in the proportion of water in the solvent mixture. This is used in the understanding of the favored/discerning solvation of cations by acetone. The influence of mixed solvent composition on the solvation of ions is discussed in tune with the composition dependence of Walden product. The influence of the mixed solvent composition on the solvation of ions has been discussed with the help of ‘R’-factor.

本文探讨了烟碱，吡啶鎓，重铬酸喹啉鎓在288-318 K在丙酮，水和各种水-丙酮（v / v）中的溶剂化行为。电导数据的分析，以获得λ ⁰是在克劳斯-布雷和Shedlovsky模型的线。λ ⁰，限制摩尔电导，增加在水在溶剂混合物中的比例增加。这用于理解丙酮对溶剂的有利/差异溶剂化。结合Walden产物的组成依赖性，讨论了混合溶剂组成对离子溶剂化的影响。借助“ R”因子已讨论了混合溶剂组成对离子溶剂化的影响。
