电解质溶液中离子浓度大小比较的方法

Comparison Methods of the Ionic Concentration in Electrolyte Solution

随着高考改革的进一步推进,化学在高考选考科目中的地位仅次于物理,居第二位,很多高校的很多专业都要求考化学。而化学学科的整体难度不是很大,但是溶液的相关知识是学生必须要掌握的。在这部分知识中,学生往往感觉溶液中离子浓度大小比较很复杂,不知如何入手。为解决学生学习此类问题的困难,我总结了以下方法。

With the further reform of college entrance examination, chemistry ranks second only to the physical chemistry in the college entrance examination in the selected test subjects. A lot of professional colleges and universities require chemical test. The relevant knowledge of solution is something students must master. In this part of knowledge,students often feel the comparison of ionic concentration is very complicated. To solve the problem, the author summarizes the following methods.
