| Abstract: | Abstract Titrimetric method for the determination of (1–100) mg/L iron(II) as pure solutions and in its dosage forms was investigated and found to offer an improvement in ease, speed and accuracy. This method is based on the direct visual titration of iron(II) with ceric amnonium sulphate and employs chlorpromazine hydrochloride in a mixture of sulphuric and phosphoric acids as a redox indicator. An interference study is carried out for the differant acids and cations. Data obtained for sevceral pharmaceuticals are reported and compared with those obtained potentiometrically. Formal redox potential was determined to be 285 mv. |
