Kronopotentiometria
Kronopotentiometria is an electrochemical technique used to study the properties of electrode surfaces and the kinetics of electrode reactions. It involves applying a constant current to an electrochemical cell and monitoring the potential difference between the working electrode and a reference electrode as a function of time. The resulting plot of potential versus time is known as a chronopotentiogram.
As the constant current is applied, the concentration of electroactive species at the electrode surface changes.
The shape and features of a chronopotentiogram can provide valuable information. For instance, a sudden steep
Kronopotentiometria can be used to determine diffusion coefficients, rate constants for electrode reactions, and to study
