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.《2013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
Knowledge of ionization balance in teaching materials is an important high school chemistry basic theory, both learning focus, but also learning difficulties, but also the hot college entrance examination from the actual situation of teaching, even the high school students, there are many students Part of the knowledge is ambiguous and does not seem to understand. "The Chemistry Section of the 2013 Comprehensive Examinations of Chemistry section clearly defines the concept of electrolytes and non-electrolytes, electrolytes and electrolytes; understanding the concept of ion reactions; understanding the concept of electrolyte ionization balance; Ionization, pH and other concepts; understand the principle of salt hydrolysis, salt solution to understand the acid-base
