Ling, Yizhou; Chen, Pengwen; Li, Juan; Zhang, Junyao; Chen, Kai – Journal of Chemical Education, 2020
This paper proposes an experiment in which students build microdevices for conveniently electrolyzing water and use image recognition and processing technology to measure the volume of gas generated during the reaction in a noncontact way. Taking advantage of three ratio relationships between (i) gas volume and the area of bubbles, (ii) the…
