络合物溶液平衡的深入研究对于分析化学和溶液化学的多方面应用(如湿法冶金,电镀等)都是非常必要的。为此,首要的任务是需要正确地阐明和计算溶液中络合物的组成和稳定常数。当络合物中的配位体是多元弱酸时,由于氢离子和金属离子都有与弱酸阴根结合的倾向,因此,在平衡体系中除了含有金属与阴根的正常络合物而外,还可能形成各种金属氢合络合物。在许多研究工作中,这类络合物的形成往往被忽略,致使结果不够准确,显然,这是应该引起重视的。遵照毛主席关于“洋为中用”的教导,本文主要根据文
In-depth study of complex solution balance is very necessary for many aspects of analytical chemistry and solution chemistry (such as hydrometallurgy, electroplating, etc.). For this reason, the primary task is to correctly interpret and calculate the composition and stability constants of complexes in solution. When the complex ligands are polybasic weak acids, hydrogen ions and metal ions tend to bind to the weak acid anion, therefore, in the equilibrium system, in addition to containing normal complexes of metal and anion, It is also possible to form various metal hydrogenated complexes. In many research work, the formation of such complexes is often neglected, leading to inaccurate results. Apparently, this should be taken seriously. Following Chairman Mao’s teachings on “using foreign as a medium”, this article mainly bases on the text
