摘 要:本文根据作者早先提出的方法以及实验测出的络合物生成反应平衡常数,对铅—氯离子—水系在高离子强度(I=5)及升温(25°~75℃)条件下的平衡进行了研究。文中特别对E-log[Cl~-]图以及由此导出的氯化铅溶解度曲线及其冷却结晶特性进行了详细的分析和讨论,得出了一系列有用的数学式。
Abstract: According to the method proposed in the authors previous works and the equilbrium constants of the complex formation reactions measured by one of the authors, equilibria in the lead-chloride ion-water system at highionic strength (I = 5) and elevated temperatures (25°~75℃) have been studied. Particularly the E-log [Cl~-] diagram and the derived solubility curves of lead chloride as well as its characteristics during the crystallization on cooling are analyzed and discussed in detail, a series of useful expressions having been deduced.
