摘要:
本文在Pb(Ⅱ)—Cl-配位体系的热力学研究中,应用Pitzer方程计算高浓、复杂的配合物溶液的活度系数.在无支持电解质存在下,设计安排了无液接电势的电动势法,测算了Pb(Ⅱ)—Cl-体系在35℃配位反应的热力学平衡常数以及配离子的活度系数式中的维里系数值.计算了25℃时热力学平衡常数和不同离子强度下的浓度平衡常数.成功地预测了25℃时PbCl2在NaCl溶液中的溶解度.
Abstract:
The thermodynamic properties of lead chloro complexes in aqueous solution are studied using a cell containing no liquid potential. The measurements performed at 35℃ and no supporting electrolyte is added to fix ionic strengths. The Pitzer’s equations are used for calculating the activity coefficents of ions in the solution, The thermodynamic formation constants,as well as the virial parameters ,or activity coefficents,of the four complexes PbCl+ ,PbCl2,PbCI3- and PbCl42- are determined. Further more,stability constants at 25℃,and at ionic strengths of zero to 5 m are calculated.The solubilities of PbCI2 in aqueous NaCI solution up to the concention of 5 m are also successfully calculated.
