Kinetics and mechanism of reduction of fe (III) salicylate complex by hydroquinone.
Pak J Pharm Sci Nov ;24(1):31-5.

The violet color complex FeSal+ was prepared by reaction of Salicylic acid and Ferric Chloride in acidic medium up to pH 3.5 in formate buffer at ionic strength 0.1 M. Reduction kinetics of FeSal+ complex at pseudo first order condition have been studied spectrophotometrically by a reductant i.e. Hydroquinone. Reduction behaviour shows that reduction is much fast and pH dependent. A mechanism to account for observation is also proposed along with the rate law.
