离子反应是高考的热点,是中学化学教学的核心内容,考察形式有离子之间能否共存、离子反应方程式的书写及正误判断、离子检验及推断。离子反应在高考试题中以选择题、填空题的形式出现,还有穿插到工业流程题、实验题之中。在复习中我们必须正确的掌握电解质、非电解质等基本概念,还要在练习、考试中注意归纳总结,更加熟练的掌握相应的知识规律。离子共存小结:
Ionic reaction is a hot spot in college entrance examination, which is the core content of chemistry teaching in middle school. It examines the form of ion coexistence, the writing of ion reaction equation, the positive and the negative judgment, the ion test and the inference. Ion reaction in the entrance examination questions to multiple-choice questions, fill in the blank form, as well as interspersed to the industrial process problems, experimental questions. In the review, we must correctly grasp the basic concepts of electrolyte, non-electrolyte, but also in practice, exams and summarize, more familiar with the rules of knowledge. Ion coexistence Summary:
