摘要:

电池符号、电极电势和电极极化是物理化学电化学教学中三个非常重要的知识点。本文以极易记忆的“数轴”为模型,阐述了数轴在这三个方面教学中的妙用。基于实例详细说明了如何以数轴模型理解记忆电池符号的规定、电极电势的大小及应用和电极极化的概念及应用。

关键词: 数轴, 电池符号, 电极电势, 电极极化

Abstract:

Battery symbols, electrode potential, and electrode polarization are very crucial in the teaching of electrochemistry. Using the "number axis", which is an extremely simple model, we can easily teach these three subjects to students. We exemplified the applications of the number axis model to understand the battery symbols, the electrode potential, and its applications, as well as the concept of electrode polarization and its applications.

Key words: Number axis, Battery symbol, Electrode potential, Electrode polarization
