    THE DETERMINATION OF IRON BY SPECTROPHOTOMETRY INTRODUCTION In this experiment, the red-orange colored complex formed between iron(II) and 1,10- phenanthroline (Eqn.) is used in determination of iron by spectrophotometry. Fe+3PhenH Fe(Phen)2 +3H red-orange (A 512 nm) An excess of reducing reagent, such as hydroxylamine or hydroquinone, is often used to reduce and maintain iron in +2 oxidation state. The complex, once formed, is very stable, and can be stored for a long time. Required Reading: Skoog and West (9E): Chapter...
