Microscale Experiments of Battery and Electrolysis Using Plastic Cells for Spectroscopic Analysis

Abstract

In a microscale experiment using a plastic cell for spectroscopic analysis, teaching materials of Daniell cells and an electrolyzing experiment were developed. When a plastic cell with four transparent sides was used, a reaction around the electrodes could be observed more clearly compared with a microscale experiment using ordinary well-plates. Also, it is possible for students to pay attention to a movement of an electron and an ion during an experiment using a battery and electrolyzing. Using developed teaching materials, class practice was performed. From a questionnaire, we got the opinion that reactions around the electrodes could be seen immediately, so, it was possible to consider a movement of an electron and an ion. We found that it is important that a reaction around the electrodes can be observed clearly in learning of a battery and an electrolyzing experiment when paying attention to a movement of an electron and an ion.
