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.
