Abstract: 0.5% aqueous solution of resazurin Na salt was found to be a convenient indicator for the stannometric determination of [Fe(CN)6]3-, Cr2O72-, Hg2+, Hg+, (PtCl6)2- and Os04 with SnCl2 in glycerol —ethanol at pH 9—12. The point of equivalence of the reactions under study is also detectable potentiometrically.
