与量有关的离子方程式的书写是高考试题中的常见题型,因试题涉及的基本量多而广,量的变化角度也多种多样,故正确书写该类离子方程式需牢固深厚的知识基础,因此这类题目都有较高的区分度.根据多年的教学体会,在解答这类型题时,遵循下述方法原则,逐步分析,就能快速准确地得出正确答案. 一、产物可与过量的反应物继续反应的离子反应
The writing of ion equations related to quantity is a common question type in high exam questions. Because the basic volumes involved in the questions are numerous and wide, and the quantity of angles of change are also varied, correct writing of such ion equations requires a firm and deep knowledge base. Therefore, these topics have a high degree of differentiation. According to many years of teaching experience, in answering this type of questions, follow the following method principles, and gradually analyze, you can quickly and accurately draw the correct answer. First, the product can be excessive The reactants continue to react with the ionic reaction
