对于无机化合物在水中的溶解度与离子极化作用的关系,前人有过不少论述和经验计算法,但总的误差均较大。本文试图从离子的基本性质——离子电荷 Z、离子半径 r((?))、离子的外层电子结构出发,提出一种较为简便、总误差较小的计算法,表示氢氧化物(?)K_m 与离子极化间的定量关系。决定无机化合物的溶解度的关键问题是离子极化作用。在离子晶体中,可把晶格看成是由带相反电荷的阴、阳离子堆砌构成的。每个离子一方面作为带电体使邻近离子发生变形,另一方面在周围离子的作用下,本身发生变形,离子的相互极化彼此改变了对方的电荷分布,导致离子间距离的缩短和轨道的重叠,降
For the relationship between the solubility of inorganic compounds in water and ion polarization, there have been many expositions and empirical calculations, but the total errors are large. Based on the basic properties of ions, such as ion charge Z, ionic radius r ((?)), And the electronic structure of the outer layer of ions, a simpler method with smaller total error is proposed. ) K_m and ion polarization quantitative relationship between. The key issue in determining the solubility of inorganic compounds is ion polarization. In ionic crystals, the lattice can be viewed as being composed of oppositely charged anionic and cationic layers. On the one hand, each ion acts as a charged body to deform neighboring ions and, on the other hand, it deforms itself under the influence of surrounding ions. Mutual polarization of ions changes the charge distribution of each other, resulting in a shortened distance between ions and orbital Overlap, drop
