Potentiometry pdf notes
Web5 Jan 2024 · Chronopotentiometry (CP) is a galvanostatic method in which the current at the working electrode is held at a constant level for a given period of time. The working electrode potential and current are recorded as a function of time. Researchers employ this method to study chemical reaction mechanisms and kinetics.
