有关电解质溶液的知识是高中化学基础理论部分的重要内容,既是高中化学的重点,也是难点,还是近年来各地高考的热点之一.由于一般规律中有特殊,并且有些概念还极易混淆,因此在学习有关电解质这部分知识的过程中,在掌握一般规律的同时,还要了解特例及一些“不一定”的情形,以防错误的发生.为此对其进行系统地归纳如下,希望对学生学好这部分知识能够有所启迪和帮助.对于下面这些特殊情形,务必搞清楚.1.强极性共价化合物不一定是强电解质,例如HF、H2O等
The knowledge of electrolyte solution is an important part of high school chemistry theory, which is not only the focus of high school chemistry, but also the difficulty, but also one of the hot spots in the college entrance examination in recent years.Because there are some special laws, and some concepts are also easily confused, In the process of learning about this part of the electrolyte, while mastering the general law, we must also understand the special cases and some cases of “not necessarily” to prevent mistakes from occurring. To learn this part of the knowledge of students can be enlightenment and help for the following special circumstances, it is important to clarify.1 Strong polar covalent compounds are not necessarily strong electrolytes, such as HF, H2O, etc.
