电化学的知识与日常生活、工农业生产密切相关,是近几年高考中的热点问题,也是同学们解题中的难点问题.电化学内容包括原电池、电解池、电镀池三部分.在初学三部分内容的时候,大多数同学都能分得清三种装置,正确解答问题.可是综合性试题出现后,三部分知识就混淆在一起.同学们就不容易分辨究竟是什么装置,应该用什么原理,怎样着手去解决问题,电极方程式如何书写等.
The knowledge of electrochemistry is closely related to daily life and industrial and agricultural production. It is a hot issue in the college entrance examination in recent years and it is also a difficult problem for students to solve problems. The electrochemical content includes three parts: primary battery, electrolytic cell, and electroplating pool. When learning the three parts of the book, most students can clearly identify the three devices and answer the questions correctly. However, after the comprehensive test questions appear, the three parts of the knowledge are confused together. The students will not be able to easily distinguish what the device is. What principle, how to proceed to solve the problem, how to write the electrode equation, etc.
