无机物在水溶液里发生的反应大部分属于离子反应,离子反应和离子方程式在高中化学课本中,虽然仅占一节课的内容,但它的地位却是十分重要的,不仅是高中化学教学的核心概念之一,也是历年高考考查的一个重点知识块。其中有一种较难的类型就是酸式盐与碱反应的离子方程式的判断与书写。 Most of the reactions of inorganic substances in aqueous solution belong to the ion reaction, ion reaction and ion equation in high school chemistry textbooks, although only a class content, but its status is very important, not only high school chemistry teaching One of the core concepts, but also a key knowledge of the college entrance examination examination over the years. One of the more difficult types is the determination and writing of ionic formulas for acid salts and bases.
