一、教学目标1.知识与技能(1)理解水的电离、水的电离平衡,了解Kw的含义。(2)掌握c(H+)、pH与溶液酸碱性的关系。2.过程与方法(1)通过对Kw的分析,加深对弱电解质电离平衡的认识,了解一般与特殊的辩证关系。(2)通过对溶液酸碱性的分析,培养学生敢于质疑、勤于思索、逐步提高独立思考的能力。 First, the teaching objectives 1 knowledge and skills (1) understand the ionization of water, water ionization balance, understand the meaning of Kw. (2) master the c (H +), pH and the relationship between pH and solution. 2. Processes and Methods (1) Through the analysis of Kw, we deepen our understanding of the ionization balance of weak electrolytes and understand the general and special dialectical relations. (2) By analyzing the acidity and alkalinity of the solution, students can dare to question, diligently think, and gradually improve the ability of independent thinking.
