比较电解质溶液中离子浓度大小的这种题型,高考化学试卷几乎年年涉及。决定离子浓度大小的因素包括:物质的量浓度、物质溶解度、电解质的电离程度、盐的水解、化学反应、温度等。比较溶液中离子浓度大小的依据为:1.应用电离平衡、水解平衡、溶解平衡等知识比较离子浓度的大小。 Comparing the size of the ion concentration in the electrolyte solution, the college entrance examination chemistry paper is involved almost every year. Factors that determine the size of the ion concentration include: concentration of the substance, solubility of the substance, degree of ionization of the electrolyte, hydrolysis of the salt, chemical reaction, temperature, and the like. The basis for comparing the ion concentration in solution is: 1. Apply ionization balance, hydrolysis equilibrium, dissolution balance, and other knowledge to compare the ion concentration.
