离子共存问题作为高中化学的重点和难点,是历届高考化学科目的必考课题之一。离子作为物质组成部分的最基本单元之一,在高中化学学习任务中占有关键地位,因此在人教版高中化学的教学中需要对离子共存问题进行详细讲解和分析。本文以人教版教材为例,分析高中化学的离子共存问题,进一步指出学生的学习要点和高考复习重点,希望能对高中学生在学习化学的道路上起到一定的帮助和参考。 Ion coexistence issues as the focus of high school chemistry and difficult, is the subject of the previous college entrance examination chemistry one of the subjects. As one of the basic units of material component, ion plays a key role in high school chemistry learning tasks. Therefore, it is necessary to explain and analyze ion coexistence issues in the teaching of chemistry in PEP. Taking the PEP as an example, this paper analyzes the ion coexistence problems in high school chemistry, and further points out the key points for students ’study and the emphasis of college entrance examination review. It hopes to help and reference the high school students’ learning chemistry.
