چکیده
|
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.
