在经典酸碱理论的基础上,劳伦斯,路易斯相继提出酸碱质子理论和酸碱电子理论,将酸碱概念推广。从而扩大了人们对酸碱的认识范围,再不局限于含氢元素存在于水溶液中的一类物质。有一些特定的因素说明酸性的强弱,本文仅讨论影响无机含氧酸强度的因素。 影响无机含氧酸强弱的因素,目前许多文献上都没有统一解释,各持己见.因都有一定的实验基础,也能解决一定的问题。许多事实说明,无机含氧酸的结构是影响强度的主要因素。当然,外部条件也有一定的影响。下面从以下几个方面加以讨论。
On the basis of classical acid-base theory, Lawrence and Lewis have put forward the theory of acid-base proton and the theory of acid-base electron to popularize the concept of acid-base. Thereby expanding the range of people’s understanding of acid and alkali, not limited to the hydrogen-containing elements exist in aqueous solution of a class of substances. There are some specific factors that indicate the strength of the acid. This article discusses only the factors that affect the strength of inorganic oxyacids. At present, many factors that affect the strength of inorganic oxyacid do not have a unified interpretation, they all see their own opinions, because they have some experimental basis, but also can solve certain problems. Many facts show that the structure of inorganic oxygen acids is the main factor affecting the strength. Of course, external conditions also have a certain impact. The following discussion from the following aspects.
