CHEM 141 Spectrometric Determination of Iron Concentrations
iron. The reaction between them is: 22 3 ( ) [( ) ]C H N aq Fe C H N Fe 12 8 2 12 8 2 3 o The resulting solution has a red-orange color. The reaction you just wrote is for Fe+2 only, but iron can be either Fe+2 or Fe+3, and we're supposed to measure the total iron. How do we deal with this problem?
