电解质溶液中离子浓度大小关系判断,涉及知识点多、综合性强,侧重学生的逻辑推理能力考察,既是高中化学的教学难点,也是高考中的高频考点。本文尝试,以高中学生能认知的程度大小比较为基础,采用模糊比较的方法,来较快的判断溶液中离子浓度大小关系。 Electrolyte solution in the determination of the relationship between the size of the ion concentration, involving more knowledge, comprehensive, focusing on the logical reasoning ability of students, both high school chemistry teaching difficult points, but also the college entrance examination in high frequency test centers. This paper attempts to high school students to recognize the degree of comparison based on the size, the use of fuzzy comparison method to quickly determine the relationship between the size of the ion concentration in solution.
