无机含氧酸是数量较多的一类重要化合物。不同的含氧酸其酸性强弱各不相同,但却存在一定的规律。许多化学工作者曾提出一些定性解释[1][2][3][4],或定量计算[5][6][7][8]。本文将首先简述无机含氧酸强度的有关论述,再从酸的Pk值与成酸元素的核电荷数(Z),电子层数(n)以及影响含氧酸强度的其它结构因素方面进行探讨,提出更简便和计算结果更接近实验值的计算公式。 Inorganic oxygen acids are a large number of an important class of compounds. Different acids have different acidity, but there are certain rules. Many chemists have proposed some qualitative interpretations [1] [2] [3] [4], or quantitative calculations [5] [6] [7] [8]. This article will first briefly describe the inorganic oxyacid strength of the discussion, and then from the acid Pk value and acid into the nucleus charge number (Z), the number of electron layers (n), as well as the impact of the strength of oxyacid other structural factors Explore and propose the calculation formula that is more simple and the calculation result is closer to the experimental value.
