Abstract

The reaction of hexaquomanganese(III) ion with hydroquinone, p-aminophenol, metol, pyrocatechol, resorcinol, and phloroglucinol was studied. It has been found that the first three substances are oxidized quantitatively with the exchange of two electrons to the corresponding quinone compounds and that this reaction can be employed for direct or indirect titrimetric determination of these substances. On the other hand, pyrocatechol, resorcinol, and phloroglucinol are oxidized nonstoichiometrically with a deeper destruction of the aromatic system, which prevents analytical use of these reactions.
