Abstract

The mandelic acid oxidation by vanadium (V) in sulfuric acid medium was studied at 303 K. The reaction rate was determined spectrophotometrically by means of the formation of vanadium (IV) at 760 nm. The oxidation reaction showed first order dependence in terms of vanadium (V)The mandelic acid oxidation by vanadium (V) in sulfuric acid medium was studied at 303 K.
