As an application of A. C. polarography, silver nitrate titration with silver electrode and neutralization titration with antimony electrode were carried out. In the case of silver electrode, it is desirable that the surface area of the electrode be small, concentration of independent electrolyte be large, and the frequency be low. In the case of antimony electrode, it is desirable that the surface area of the electrode be small and frequency low, but inversely, concentration of independent electrolyte should be small. Sensitivity of both electrodes as inductive titration was not as good as that of platinum electrode. However, the two electrodes showed specific titration results and were successfully applied for A. C. polarography.
