摘要
以反应的耦合与浓度商为核心概念,以弱电解质的电离、难溶电解质的配位溶解等为问题情境,引导学生基于反应间相互作用视角认识水体系中的物质转化程度。
Based on the coupled thoughts and concentration quotient,this paper presented an example of teaching practice on the topics of ionization of water,week acid&base,salts hydrolysis,precipitate and dissolution.The course was designed to help students understand the acid-base reaction and the degree of substances equivalence in an aqueous system,from a view of dynamic reaction in a chemical process.
