溶度积常数是沉淀溶解平衡中的难点内容,部分省市高考考试说明中明确要求“用溶度积常数进行相关计算”。现结合近几年各省市高考试题及模拟试题,对溶度积常数计算的常见题型及考查方式进行归纳,并列举典型例题进行分析,供广大师生参考。一、沉淀反应的有关计算1.判断沉淀能否产生通过比较溶度积和离子积的相对大小,
The solubility product constant is the difficult content in the equilibrium of precipitation dissolution. In some provinces and cities, the description of college entrance examination clearly requires “Correlation calculation with solubility product constant”. Now with the provinces and cities in recent years, college entrance examination test questions and simulation questions, the common problems of the solubility product constant calculation and test methods are summarized, and a typical example cited for analysis for the majority of teachers and students for reference. First, the calculation of the precipitation reaction 1. To determine whether the precipitate produced by comparing the solubility product and the relative size of the product,
