metadata.value: In the experiment, an electrolytic cell with electrodes of different area was used. To study the
  current-voltage characteristics, a pulse-based measuring circuit was developed and implemented.
  It became possible to carry out an experiment with a small average current due to the large
  duty cycle between the measuring pulses. Such an approach made it possible to neglect chemical
  reactions in the near-electrode layers of the space charge, and also to obtain reproducible measurement
  results. Measurements of current-voltage characteristics in 1% KCl solution were carried
  out. In the experiment, symmetric current-voltage characteristics were obtained. A numerical
  derivative of I (U) was found. The shapes of the curves I(U) and I (U) were discussed. The
  calculations are given showing that for a symmetric current-voltage characteristic the current is
  electrically proportional to the hyperbolic sine. Accordingly, the current derivative is a hyperbolic
  cosine. A technique for determining the concentration of ions in simple electrolytes is presented.
  The error of the presented method is 10–12%. The proposed method of measurement makes it possible to obtain current-voltage characteristics without the use of large-size installations containing
  mercury. Refs 5. Figs 1.
