摘要
本文提出了一个计算无机含氧酸pK值的新经验公式.此式反映了影响酸强度的三个主要因素,形式简单,便于应用.特别是它的各类偏差小,对于64个有实验值的含氧酸的pK值,其绝对平均偏差为0.377.而绝对偏差|△pK_i|>1.0的仅占4.7%.
In this paper, we present a new empirical formula for competing pK values of inorganic oxygen-containing acid. The formula reflects three main factors affecting acidity, Its form simple and convenient for the use. What is more important, it has small deviation. For 6.4 oxygen-containing acids with pK experimental values, its absolute mean deviation is 0.377 and its absolune deviation |△pki| >1 is only 4.7%.
