| Abstract: | Either of two quinoidal structures might be formed in the oxidation of 2-hydroxy-4-amino-4'-miethoxydiphenylamine (2-Oxyvariamine Blue). It is shown that it is the paraquinoidal holoquinone that is formed. The ascorbimetric determination of certain oxidising agents (I2, Br2, IO3−, BrO3−, CrO42−), using 2-Oxyvariamine Blue and a hexacyanoferrate(II)hexacyanoferrate(III) system is described. |
