Chronopotentiometry is a highly specialized term that refers to a specific electrochemical technique used to measure the time-dependent changes in electrode potential. Although there are not many synonyms for this precise term, one possible alternative could be "time-resolved electrochemical analysis" or "time-domain electrochemistry." Other options might include "chronoamperometry" or "cyclic voltammetry," which are related techniques with similar principles but different experimental protocols. Ultimately, the best synonym for chronopotentiometry will depend on the specific context in which the term is used and the level of technical precision required for that application.
