电解质如KCl等的水化热,可由公式△H_k~+△H_(cl)-=△H_L-Ug计算求得。但是,单种离子水化热如△H_K~+或△H_(cl)-等不能由实验直接测得。但可根据一定的假定模型进行理论计算,如Born模型,水四极子模型等。本文重点讨论实验相对水化热和实验绝对水化热的计算,为溶剂化理论的结构模型建立一系列可供比较的离子实验水化热的数据,同时阐明一种确立实验水化热的普遍适用的方法。
Electrolytes such as KCl hydration heat, can be calculated by the formula △ H_k ~ + △ H_ (cl) - = △ H_L-Ug calculated. However, a single ion hydration heat such as △ H_K ~ + or △ H_ (cl) - can not be directly measured by the experiment. However, theoretical calculations can be made based on certain assumed models, such as the Born model and the water quadrupole model. This article focuses on the calculation of the relative hydration heat and the absolute hydration heat of the experiment, and establishes a series of comparable hydration heat data for the structural model of the solvation theory. At the same time, it illustrates a common way to establish experimental hydration heat Applicable methods.
