任何稀水溶液中都存在着水的电离平衡，在不同的水溶液中水的电离程度不同。尽管ＫＷ在一定温度下是一个定值，但由于水的电离度受酸、碱度的影响。因而将水的电离平衡与溶液的酸、碱度的关系作为重要的知识点归纳整理，进行专题复习，有利于培养学生的辩证思维能力。一、... The ionization balance of water exists in any dilute aqueous solution, and the degree of ionization of water in different aqueous solutions is different. Although KW is a constant value at a certain temperature, the degree of ionization of water is affected by the acid and alkalinity. Therefore, the relationship between the ionization balance of water and the acidity and alkalinity of the solution is summarized as an important knowledge point, and the review of the topics will help cultivate students’ dialectical thinking ability. one,...
