在高中化学中讲述了原电池、电解和电镀的反应,它们都是在电极上发生的氧化还原反应,同时也说明原电池是把化学能转变为电能的装置.学生在学习过程中对上述概念及有关原理容易混淆,如果用一个以原电池作为电源进行电解和电镀的实验,来说明有关概念以及对化学能和电能的相互转化,对原电池和电解池的区别就迎刃而解,学生对所学的知识不仅容易理解而且掌握也牢固. The reactions of galvanic cells, electrolysis, and electroplating are described in high school chemistry. They are all redox reactions that take place at the electrodes. They also show that galvanic cells are devices that convert chemical energy into electrical energy. Students learn the above concepts during the learning process. The relevant principles are confusing. If an electrolysis and electroplating experiment is performed using a primary battery as a power source to illustrate the concept and the mutual transformation of chemical energy and electric energy, the distinction between the primary battery and the electrolytic cell will be solved and students will learn about it. The knowledge is not only easy to understand but also strong.
