Mercurimetric Determination of Chloride

the operation of water and waste treatment plants, personnel with a wide variety of backgrounds are required to make laboratory tests. It is important, therefore, that any routine quantitative determination be simple and accurate, and that any endpoint involved be sharp and well denned. The Mohr and Volhard methods (I) currently employed for the determination of chloride ions do not meet these specifications adequately. The more generally accepted silver nitrate-potassium chromate titration method
