Determination of Fe2+ next to Fe3+ (cerimetric)In samples that contain both iron (II) and iron (III) ions, the content of Fe2+ in addition to Fe3+ can be determined by titration with Cerium (IV) sulfate.
Titration Determination of Fe3+ (complexometric)Iron (3) forms a very stable complex with EDTA even at low pH Values.
