Abstract
Bromate and chlorate ions were determined via potentiometric titration with silver nitrate after reduction to bromide and chloride ions, res pectively, with sodium nitrite. The precision of the analysis was less than 0.6% in all instances. It is also shown that chlorate ions can b e determined in the presence of perchlorate with good precision. These methods made it possible to determine bromide and bromate ions and al so chloride and chlorate ions simultaneously.
