ferrous tris(1,10-phenanthroline)iron(II) or [Fe(phen) 3]2+, is a bright orange color. A 3D model of the structure of the complex is shown in Figure 2. In addition to its Fe2+ (ferrous ion) form, iron also can exist in a Fe3+ (ferric ion) form. To perform a total iron measurement, it is essential to reduce any Fe3+ in solution to Fe before adding the phenanthroline to form the complex. The
Iron, when extracted from iron ore such as haematite containing iron(III) oxide, Fe 2 O 3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron(III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures. The steps are: 1. Concentration of Ore. 2

In the current experiment, potassium dichromate, K2Cr2O7, is used as the titrant to determine the amount of iron in an ore sample. Since the potassium dichromate is ionized in solution, the redox reaction taking place during the titration can be written as: 6 Fe2+ + Cr2O72- + 14 H+ 6 Fe3+ + 2 Cr3+ + 7 H2O. In this reaction, each Fe (II) ion
