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
