O-Anisidine as Indicator in Titrimetric Determination of Iron (II) in Pharmaceutical Formulations and Water Samples
Abstract: Inspite of the beautiful red coloured oxidized product of O-anisidine, the studies on its application in analytical techniques are scanty. So, authors have taken up the investigation on the utility of O-anisidine as a new Analytical reagent in the bromatometric-Indicator reaction. The detailed reaction on the potassium bromate and O-Anisidine has enabled the authors to utilize O-Anisidine in titration of Iron (II). Suitable conditions have been established with different acids viz., hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid to give sharp colour change at the equivalence point. This method could be used successfully for determination of the Iron (II) content of Spiked water and Pharmaceutical samples. The results obtained are in good agreement with the values obtained by standard methods.
