Anodization of Bismuth: Measuring Breakdown Voltage and Optimizing an Electrolytic Cell
Nagel, Thomas; Mentzer, Casey; Kivistik, P. Mike
Journal of Chemical Education, v96 n1 p110-115 Jan 2019
This experiment provides students with a thorough understanding of electrolysis and the parameters that most greatly impact optimization of this process. In this laboratory exercise, students will focus on the anodization of bismuth metal to develop thin oxide films. When designing an electrolytic cell devoted to anodization, there are several major factors necessary for the optimization of the cell and these are explored in this experiment. Current density, electrolyte concentration, breakdown voltage, and anodization rate all impact development of these anodic oxide films. This exercise emphasizes the interrelationships between these critical factors and the best way to optimize an electrolytic cell. This procedure is carried out with standard chemicals and widely available technology to allow for an inexpensive and accessible laboratory experiment.
