在人类的生活和生产中存在着多种化学反应,其中氧化还原反应就是一个重要的分支。电化学是研究电能与化学能相互关系的科学,而氧化还原反应正是学习电化学知识的基础,两者在高考中均占据着相当重要的地位,所以在高中的化学学习中要解决好电化学问题,首先要理清氧化还原反应的原理,再将此原理应用到电化学中的原电池和电解池工作原理分析,是非常必要的。 In human life and production there are a variety of chemical reactions, including redox reaction is an important branch. Electrochemistry is a science that studies the relationship between electrical energy and chemical energy, and the redox reaction is the basis for learning electrochemical knowledge. Both of them occupy a very important position in college entrance examination. Therefore, in high school chemistry learning, Chemical problems, first of all to clear the principle of the oxidation-reduction reaction, and then apply this principle to electrochemical cells and electrolysis cell working principle analysis is very necessary.
