AB-008 Potentiometric titration of hypochlorite, chloride and chlorate in mixtures  
Potentiometric titration of hypochlorite, chloride and chlorate in mixtures

Potentiometric titration methods are described for the determination of hypochlorite, chloride and chlorate in mixtures. Hypochlorite is titrated in alkaline solution with arsenite. Then, after acidification of the sample solution, the total chlorides (chloride plus chloride formed from hypochlorite) can be determined using silver nitrate. Chlorate is first reduced to chloride under acidic conditions with iron(II) ions and then also titrated as chloride. The individual components can also be determined by the methods described here.
