The kinetics and mechanisms of the reaction of azo dye methyl orange with . OH, e-aq and . ... These results shed light on the degradation mechanism of hydrosoluble azo-dyes in aqueous solution and hence provide the theoretical foundation for the treatment of the water contaminated with this class of compounds.

1. Methyl Orange is an acid-base indicator. In dilute solution pH > 4.4 it is yellow. At pH = 3.2 the solution appears red. Draw a structure of the species that is formed at the lower pH if the acid proton adds to the azo nitrogen atom adjacent to the aromatic ring containing -SO3- group.

Catalysis is attributed to acid/base-assisted tautomerization of cis-ammonium ions (formed by rapid protonation of cis-methyl orange generated upon photochemically induced trans−cis isomerization) into cis-azonium ions.
