摘    要：本文根据同时平衡原理和电中性原理对Sb（Ⅲ）-Cl^--H₂O系,Sb（Ⅲ）-Me（Ⅰ）-Cl^--H₂O系和Sb（Ⅲ）-Zn（Ⅱ）-Cl^--H₂O系进行了常温下水解平衡的热力学分析.计算及绘制了[Sb³⁺]_T,[H⁺]与[Cl^-]_T,[Me⁺]或[Zn²⁺]的热力学关系图.经验证,彼此符合较好.又将计算及实验数据分别回归拟合,得出了相应的数模关系.

Abstract: In terms of the principles of simultaneous chemical equilibrium and electronic charge neutrality, the thermodynamic analyses of hydrolytic equilibria at room temperature have been made for the systems of Sb（Ⅲ）-C1^--H₂O, Sb（Ⅲ）-Me（Ⅰ）-Cl-H₂O and Sb（Ⅲ）-Zn（Ⅱ）-Cl^--H₂O in this work. The calculation of thermodynamic data and the ploting of [Sb³⁺]_T or [H⁺] versus [C1^-]_T and [Meⁿ⁺] on the hydrolytic equilibria in the systems were carried out. The obtained data and curves have been correlated with the experimental data, and there is a good agreement between them. The respective regressions of calculated and experimental data have given the relationship of the numeral models.
