STUDYING THE REAGENT PROPERTIES OF INDIGO

New and modern areas of analytical chemistry in the field of detection of non-ferrous metals are currently being developed. This article presents methods for the spectrophotometric determination of manganese ion, one such metal. It is important to note that the colored substance indigo, which belongs to the class of organic compounds, was used as a reagent. The optimal conditions for analysis were found , the composition and stability constants of the manganese complex (+ 2 ) with the analytical reagent indigo were determined
