离子反应贯穿在整个高中化学之中,是高考必考知识点之一。要求能较熟练地掌握在水溶液中(不同条件下)离子能否大量共存的特点和规律;要求能正确书写离子反应方程式。考试中主要题型有:离子是否共存的判断,离子反应方程式的书写、判断正误。因此复习时需要从理解离子反应的原理和离子反应发生的条件入手,从而掌握离子能否大量共存的判断方法及依据和离子反应方程式书写的技巧及规律并能进行迁移和灵活运用。
Ion reaction throughout the high school chemistry, is one of the entrance exam knowledge point. Requires a more skilled grasp of the aqueous solution (under different conditions) ions can coexist in a large number of features and laws; required to correctly write the ionic reaction equation. The main types of questions in the exam are: Judgment of coexistence of ions, ion reaction equation writing, judging correct. Therefore, the review needs to understand the principle of ion reaction and the conditions of ion reaction to start, in order to grasp whether a large number of ions coexist judgment method and basis and ion reaction equation writing skills and rules and can migrate and flexible use.
