对于无机含氧酸强度变化的规律性,前人曾作过不少研究,他们从不同的角度出发,利用不同的键参数,归纳出各自的经验公式和近似规律。不可否认,由于人们对经验公式的不断改进,使得计算结果越来越接近实验值。但是另一方面公式中引入的参数也越来越多,因此从某种意义上来说,又使公式的物理意义显得比较模糊。我们在前人工作的启发下,提出了一个形式比较简单、计算结果更接近实验值的计算无机含氧酸强度的经验公式,公式只包含了少数几个重要的结构因素,并能体现一定的物理意义。
For the regularity of the change of strength of inorganic oxygen acids, many studies have been made beforehand. From different perspectives, they use different key parameters to sum up their own empirical formulas and approximate rules. Admittedly, due to the continuous improvement of empirical formula, the calculation results are getting closer to the experimental value. But on the other hand, there are more and more parameters introduced in the formula, so in a sense, the physical meaning of the formula appears to be rather vague. Inspired by the previous work, we propose an empirical formula for calculating the strength of inorganic oxyacids with a simpler form and closer to experimental results. The formula contains only a few important structural elements and can reflect certain Physical meaning.
