Abstract
The concept of "abnormal decomposition potential" as described by Liang et al. (J. Chem. Educ. 1999, 76, 444) is imprecise and of little relevance in modern electrochemistry. Complete current- potential curves can be calculated and they show why such decomposition potentials are smaller than standard potentials. Disproportionation reactions are not needed to explain this phenomenon, which is the natural consequence of current-vs-potential behavior, and are of little importance in understanding the redox chemistry of halogen acids at concentrations at or above 10-3 M levels.
