电解质溶液中粒子浓度大小比较是历年高考的 常见题型,也是学生学习中的一个难点。它涉及到弱 电解质的电离平衡、盐类的水解平衡、电解质之间的 反应及溶液中阴、阳离子的电荷守恒、物料守恒等知 识．本文就今年化学高考题中出现的典型试题进行归 类总结,概括出不同类型的电解质溶液中粒子浓度大 小比较的解题要点。 The comparison of particle concentration in the electrolyte solution is a common question in the college entrance examination over the years, and it is also a difficulty in student learning. It involves the ionization balance of weak electrolytes, the hydrolysis balance of salts, the reactions between electrolytes, the conservation of charge of anions and cations in solutions, and the conservation of materials. In this paper, the typical questions appearing in this year’s college entrance examination are summarized, and the key points for solving the problem of particle concentration in different types of electrolyte solutions are summarized.
