In the preceding communications of this series,1,2 the results of titrations with ferricyanide were given. In the present paper new titrations with hypobromite are described. This reagent has already been used for the determination of ammonia, ammonium salts and urea,1 23 for the determination of arsenites,4 iodides,5 thiocyanates,6 7and thiosulfates.5,7Applying the potentiometric control, we have repeated the mentioned determinations8 9and also tried the possibility of the titration of yet other reduction-oxidation systems. Efforts to bring about a direct oxidation of plumbous, ferrous and chromic salts were without success.
