Ferrous sulfate was used for many centuries to manufacture inks and wool/fabric dyeing; particularly it was used to obtain indigo dye. PART II. A common example is the redox titration of a standardized solution of potassium permanganate (KMnO4) against an analyte containing an unknown concentration of iron (II) ions (Fe2+). ⚛ Question - Titrant used in the assay of ferrous sulphate IP 1996 is ☑ Answer - Ferrous sulphate . One mole of the unknown ferrous compound reacts with one mole of ceric sulphate. In analytical chemistry, the titrant is a solution of known concentration that is added to another solution to determine the concentration of a second chemical species.The titrant may also be called the titrator, the reagent, or the standard solution. As with acid-base titrations, a redox titration (also called an oxidation-reduction titration) can accurately determine the concentration of an unknown analyte by measuring it against a standardized titrant. Use this medicine (ferrous sulfate capsules and tablets) as ordered by your doctor. The subsequent procedure follows that used in the assay of Ferrous Gluconate using Cerric ammonium sulphate.
