Determination of the Iron Content Using Visible Spectrometry

It is interesting to note that iron(III) is generally useless for living systems. Many areas have soils with high iron(III) content but little or no iron(II), and thus are nonsupportive of plant life, despite their high iron content. In this experiment, the amount of iron in a vitamin tablet will be determined.
