In potentiometry we measure the potential of an electrochemical cell under static conditions. Because no current—or only a negligible current—flows through the electrochemical cell, its composition remains unchanged. For this reason, potentiometry is a useful quantitative method. cs go bunnyhop commandWitrynaPotentiometry This is the method in which the potential between two electrodes is measured while the electric current (usually nearly zero) between the electrodes is controlled.
