A. C. constant-current titration was carried out as a modification of A. C. polarization titration using platinum electrodes. Similar to the A. C. constant-voltage method reported in previous papers, it is necessary to make the variation of polarization resistance at the electrode as large as possible in order to increase sensitivity of titration and the titration curve shows a type approximately reverse of that in the constant-voltage method. The solution resistance is neglected in the constant-current method and there is no necessity of considering polarization resistance and solution resistance at the same time, as is made in the constant-voltage method. In this sense, the A. C. constant-current method is easy, both theoretically and experimentally.
