溶液中各种粒子浓度大小的比较一直是高考命题的热点,备受命题者的青睐,同时也是复习中的一个难点。它涉及电离平衡、水解平衡、电荷守恒、物料守恒和质子守恒等知识。本文通过典型例题剖析,总结概括不同类型的电解质溶液中粒子浓度大小比较的解题思路。一、大小关系1.单一溶液 The comparison of the concentration of various particles in the solution has always been the hot spot of the college entrance examination proposition. It is highly favored by propositionalists, and it is also a difficult point in the review. It involves knowledge of ionization equilibrium, hydrolysis equilibrium, charge conservation, material conservation, and proton conservation. This article through a typical example analysis, summed up the summary of different types of electrolyte solution particle concentration comparison of the problem-solving ideas. First, the size of a single solution
