难溶电解质溶解平衡作为新课标教材调整后的新增内容,既是化学平衡理论的拓展和应用,更是考生深入理解电解质溶液中沉淀的生成、转化和溶解的重要理论基础。有关溶度积的考查更成为近年来高考化学新的考查热点。下面举例说明。一、基本概念的考查例1下列说法正确的是()A.在一定温度下的AgCl水溶液中,Ag~+和Cl~-浓度的 The balance of insoluble electrolyte dissolution as a new content of the new curriculum standard is not only the expansion and application of the chemical equilibrium theory, but also an important theoretical basis for candidates to understand deeply the generation, transformation and dissolution of precipitation in electrolyte solution. The test of solubility product has become a new hot spot for examining chemistry in college entrance examination in recent years. Here’s an example. First, the basic concept of test Example 1 The following statement is correct () A. AgCl aqueous solution at a certain temperature, Ag ~ + and Cl ~ - concentration
