The document describes an experiment to determine the concentration of a ferrous ammonium sulfate (FAS) solution using potentiometric titration with a standard potassium dichromate (K2Cr2O7) solution.
We evaluated several literature-based replacement oxidants for K2Cr2O7 (potassium dichromate) and identified KIO3 (potassium iodate) as the only chemically viable alternative for thiosulfate standardizations, consistent with use of iodate by others.
