An apparatus to determine oxidation/reduction capacity of a solution using a color-changing redox indicator. In this case ceric (Ce 4+) ions at a known concentration are added to and oxidize the ferrous (Fe 2+) ions. science engineering titration Redox Titration Apparatus of Ferrous Ions by Ceric Ions
