| Abstract: | Methods based upon the quantitative electrolytic generation of permanganate in aqueous sulfuric acid solutions of manganous sulfate have been developed for the coulometric permanganatometric determination of oxalate, ferrous, and arsenious ions; the end-point being ascertained by means of colour changes of indicators. In this way coulometric permanganatometry has been established and the possibility of its large practical utilisation has been shown.Thus, by the creation of the coulometric permanganatometry, the coulomb, replacing the mass of the standard, has penetrated into still another part of analytical chemistry for measurement and standardization. |
