FIELD: physics.
SUBSTANCE: use for dynamic change of chemical potential of electrons and redox potential in liquid during chemical reaction. Essence of invention is that system for dynamic measurement of redox potential in electrolyte with limited volume includes at least one comparison electrode and at least one indicator electrode, which are immersed into electrolyte and connected to external circuit, wherein the comparison electrode is configured to freely exchange electrons with the electrolyte and has a low impedance value with respect to the impedance of the indicator electrode, comparison electrode is connected to DC voltage source or common ground potential and voltage is shifted from external circuit to it; wherein the display electrode has a high impedance value with respect to the reference electrode impedance, preventing electronic exchange with the electrolyte solution, indicator electrode is connected to external circuit for potential measurement thereon; wherein the ratio of the impedance of the measuring electrode to the reference electrode impedance is not less than 5; wherein distance between comparison electrode and indicator electrodes is not more than 1 cm, electrolyte volume does not exceed 10 cm3, and a vessel defining a volume of electrolyte, provides a high impedance value electrolyte – ground potential "earth" in relation to the impedance of the indicator electrode with a ratio of not less than 5.
EFFECT: possibility of detecting intermediate transient states and monitoring of energy change during chemical reaction.
