离子方程式是用实际参加反应的离子符号来表示的式子,所以它能揭示反应的实质.在化学试题中,除题目直接考查离子方程式的书写外,很多同学不会运用离子方程式来进行思维解题,而有些题目如果不运用离子方程式来进行分析,或过程复杂,或导致错误结论.下面将通过一些例题来阐述离子方程式的特殊运用. The ion equation is an equation represented by the ion symbol actually participating in the reaction, so it can reveal the essence of the reaction. In the chemistry test questions, many students will not use the ion equation to solve the problem except for the direct examination of the ion equation. Problems, and some topics if you do not use the ion equation to analyze, or the process is complex, or lead to erroneous conclusions. The following will explain the specific use of ion equations through some examples.
