电解质溶液中微粒大小比较的问题是高中化学的热点问题,也是高考化学复习的重难点.此类试题,由于涉及电离理论、水解理论、守恒思想、平衡思想、元素观、微粒观、定量观等理论知识和化学核心观念,可以有效测试综合应用能力和处理图表信息能力,因此已成为高考命题的热门.下面通过一个具体实例来分析:
The problem of particle size comparison in electrolyte solutions is a hot issue in high school chemistry and is also a major difficulty in chemical review of college entrance examinations. Such questions are related to ionization theory, hydrolysis theory, conservation thought, balance thinking, element concept, microscopic view, quantitative view, etc. Theoretical knowledge and the core concept of chemistry can effectively test the comprehensive application ability and ability to process the information of charts. Therefore, it has become the hot topic of the college entrance examination. The following analysis is based on a specific example:
