Cerimetric determination of dithionate and polythionates.
Ceric sulphate in a boiling strongly acidic medium oxidizes dithionate as well as tri- and tetrathionates quantitatively to sulphate. These anions may therefore be determined cerimetrically when they are present singly. A combination of the cerimetric method with other known methods (e.g. those of Kurtenacker, etc) is suggested for the analysis of mixtures of polythionates and dithionate.
