教材中电离平衡的知识是高中化学重要的基础理论,既是学习的重点,也是学习的难点同时又是高考的热点.从教学的实际情况来看,即使是高三学生,还有不少同学对部分知识模棱两可,似懂非懂.“2006年理科综合考试说明”化学部分明确规定“了解电解质和非电解质、强电解质和弱电解质的概念;理解离子反应的概念;理解电解质的电离平衡概念;了解水的电离、溶液pH等概念;理解盐类水解的原理了解盐溶液的酸碱性;了解强酸强碱中和滴定的原理等.为了帮助学生掌握好这部分知识现将有关疑点归纳如下.
Knowledge of ionization balance in teaching materials is an important high school chemistry basic theory, not only the focus of learning, but also difficult to learn at the same time is the hot college entrance examination from the actual situation of teaching, even the third year students, there are many students on the part Knowledge ambiguous, understandable. “2006 science comprehensive examination instructions” Chemical part clearly defined "understanding of the concept of electrolyte and non-electrolyte, strong electrolyte and weak electrolyte; understand the concept of ion reaction; understanding of electrolyte ionization balance concept; understanding of water Ionization, solution pH and other concepts; understand the principle of salt hydrolysis to understand the acid-base salt solution; understand the principle of strong acid and alkali neutralization titration, etc .. In order to help students master this part of the knowledge, the suspects will now be summarized as follows.
