离子作为组成物质最基本的单元之一,在高中化学理论体系中占有非常重要的位置。离子反应方程作为化学反应方程的一种,对于部分反应而言是化学反应更加本质的表达方式。同时,由于离子的带电问题和形成离子的原子或者原子团之间的反应问题,导致了很多离子无法在溶液中共存无法共存,由此,离子共存问题也成了离子化合物知识体系中一个十分重要的话题。在本篇文章中,作者通过对离子共存问题进行分类,并且对它们进行了分别分析和举例说明,希望能对高中理科生学习化学知识尤其是离子化合物之间的反应提供一定的帮助。
Ion as one of the most basic elements of the composition of matter, in high school chemistry theory system occupies a very important position. Ion reaction equation as a chemical reaction equation, for part of the reaction is a more substantive chemical reaction expression. At the same time, the problem of ionic coexistence has become a very important factor in the knowledge system of ionic compounds due to the fact that many ions can not co-exist in solution due to the ionic charge problem and the reaction between atoms or atomic groups that form ions topic. In this article, the authors classify the ionic coexistence problems and analyze and illustrate them separately, hoping to help high school science students learn chemistry, especially the reaction between ionic compounds.
