在许多文献中,早已把盐的水解尤其是金属离子水解作用的复杂性作了比较概括且又令人信服的阐明.笔者在上一篇文章中,针对金属离子的水解作用,曾提出了一经验关系式PK_h=14-PK_b+ 0.014n用以计算其水解常数.虽然应用该关系式可以计算出许多金属离子的水解常数,并大多能与实验值较好的吻合,但关系式的提出尚缺乏理论上的依据,同时由该关系式计算出的个别数值与实验值相差颇大,原因亦无法解释清楚.本文就这些问题做了一些工作,并对影响金属.
In many literatures, the complexity of salt hydrolysis, especially the hydrolysis of metal ions, has long been elucidated in a more conclusive and convincing way.In the last article, I proposed a new method for the hydrolysis of metal ions The empirical relationship PK_h = 14-PK_b + 0.014n is used to calculate the hydrolysis constants. Although the relationship can be used to calculate the hydrolysis constants of many metal ions, and most of them agree well with the experimental values, the relationship is still lacking Theoretical basis, at the same time by the relationship between the calculated individual values and experimental values quite different, the reason can not be explained clearly.This paper does some work on these issues, and the impact on metals.
