水溶液中的离子平衡是化学平衡的延伸和应用,也是高考中考点分布较多的内容之一.其中沉淀溶解平衡是新课标中新增的知识点,题型主要是选择题和填空题,许多高中生在应对强弱电解质、盐类水解、离子反应、水的电离、计算p H值问题以及酸碱度大小问题时常出现错误.为此,本文尝试对这类题型做一个小结与归纳,达到更好的掌握知识点.除此之外,也能够提高中学生的综合解题能力.现结合实例,简要地介绍几类电离平衡问题的解题方法.
Ion balance in aqueous solution is the extension and application of chemical equilibrium, but also one of the contents of the test center in the college entrance examination distribution more. Which sediment dissolution balance is the new knowledge points in the new curriculum standard, the questions are mainly the multiple choice and fill in the blank, Many high school students often make mistakes when dealing with strong and weak electrolytes, salt hydrolysis, ion reaction, ionization of water, calculation of p H value and the problem of pH value.Therefore, this paper attempts to make a summary and summary of such questions, Better master the knowledge points.In addition, it also can improve the ability of middle school students to solve problems.Considering examples, we briefly introduce several kinds of ionospheric balance problem solving methods.
