Abstract:We
investigate the electric response of an electrolytic cell of
water and KCl, limited by gold electrodes, to derive information on
the role of the electrodes in the spectra of the real and imaginary
parts of the electric impedance of the cell. Our experimental data
can be interpreted by means of the Poisson–Nernst–Planck
model with Ohmic boundary conditions for the electrodes, where the
surface conductivity is consistent with that derived by a random-walk
model for the charge exchange on the electrodes. By us… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
