The Electrical Double Layer and Its Structureproperties of such a layer are important, since they significantly affect the electrochemical measurements. In an electrical circuit used to measure the current that flows at a particular working electrode, the double layer can be viewed as a capacitor.

Chronocoulometryis is directly proportional to the current (.) and the time (.), i. e., on the quantity of electricity (.) that passes through the solution (first law). The amount of the product depends on the equivalent mass of the substance electrolyzed (second law). (In fact, Faraday’s laws are based on two fund

The rate at which it proceeds to a new steady state depends on characteristic parameters (reaction rate constants, diffusion coefficients, charge transfer resistance, double layer capacity).
