WebFeb 15, 2008 · In the classical Gouy–Chapman theory as applied to the outer double layer element in electrolyte solutions, Boltzmann’s law is invoked in assuming that, if w A → B is the work required to carry an ion of charge Q from point A in the solution to point B, then the equilibrium ionic concentrations at the two locations are in the ratio (7) c ... WebNov 18, 2024 · Ionic effects of the DLCs have sometimes been thought to be expressed by the Gouy–Chapman (GC) theory, which exhibits V-shaped capacitance vs. voltage curves. However, no V-shape has been found even in 0.05-mM salts [ 12 ]. DLC values have not been obeyed by the dependence of the square-root of concentrations predicted from the … tool to remove computer keys
