根据电极上的氧化还原反应来判别电极的阴阳极,不少初学者深感困难。为此,笔者介绍根据阴阳离子运动的方向来判别电极阴阳极的方法与实例,供教学中参考。
According to the redox reaction on the electrode to discriminate the anode and cathode of the electrode, many beginners find it difficult. For this reason, the author introduces the methods and examples of discriminating the cathode and the anode according to the direction of movement of the anions and cations for reference in teaching.
