Abstract
A novel measuring electrode for determination of the concentration of anionic species in aqueous solutions by measuring the potential difference between the measuring electrode and a reference electrode comprising a body provided with an outer surface comprised of graphite or carbon black dispersed in a chemically inert matrix, said electrode being preactivated by anodic polarization in an aqueous alkaline or acid solution, the process of activating the said electrode and a method of ascertaining the charge state of an electric accumulator by determining the strength of the electrolyte therein.
