Electrolytic capacitor to a smooth surface of the same area or the same volume. By applying a positive voltage to the above-mentioned anode material in an electrolytic bath an oxide barrier layer with a thickness corresponding to the applied voltage will be formed (formation). This oxide layer acts as dielectric in an electrolytic capacitor. The properties of this oxide layers are given in the following table: After forming a dielectric oxide on the rough anode structure, a counter electrode has to match the rough insulating oxide surface. This is accomplished by the electrolyte, which acts as the cathode electrode of an electrolytic
Standard hydrogen electrode from the previous one it was given the name 'Standard Hydrogen Electrode'. In summary, The choice of platinum for the hydrogen electrode is due to several factors: The surface of platinum is platinized (i.e., covered with platinum black) to: Other metals can be used for building electrodes with a similar function such as the palladium-hydrogen electrode. Because of the high adsorption activity of the platinized platinum electrode, it's very important to protect electrode surface and solution from the presence of organic substances as well as from atmospheric oxygen. Inorganic ions that can reduce to a lower valency state at the
