• Chlorine in tantalum metal was titrated argentometrically by the end point detections presented above. The method using test paper was reported previously {this journal, 14, 193 (1965)}. In the latter (derivative polarographic) method, the authors worked out the method by which the effect of the solubility of silver chloride could be overcome. Two drops of an ammonia, solution of the chloride was added to the sample solution, and the titration was carried out in ethanolic media (50% v/v) containing nitric acid. Well defined titration curves could be obtained by this method. Several tens micrograms of chloride ions in 100 m<I>l</I> of the sample solution could be titrated with satisfactory results.
