Excerpt from Determination of Manganese as Sulphate and by the Sodium Bismuthate MethodOf various methods considered, the bismuthate appeared most promising, and has been found to entirely fulfill the above require ments. In this method the manganese in nitric acid solution is oxidized with sodium bismuthate, of which the excess is removed by filtration through asbestos. T o the resulting permanganic acid is added a measured excess of ferrous sulphate solution, which is then titrated with permanganate of known strength and of known ratio to the ferrous solution. The investigation therefore resolved itself into a study of the methods of standardiz ing the permanganate employed in the final titration and the in¿uence of the various conditions of operation upon the results obtained by the bismuthate method.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
