Polarography with controlled current density — Chronopotentiometry at a dropping ellectrode: Part III. Experimental verfication of the theory

A large number of experiments have been communicated with regard to the operation of a polarograph which shows essentially a galvanostatic character instead of the usual potentiostatic one. A reasonable good agreement could be established between practice and theory. Finally some introductary experiments have been reported concerning phenomena connected with the absence of surfactants in the solution, and other ones observed in the presence of catalysts which promote the evolution of hydrogen.
