Question

2. What is the role of the 1,10-phenanthroline in the experiment? 3. Say a sample solution was prepared, as described in the procedure. If the procedure was followed correctly, its absorbance value ("true value") should be 0.465. However, if a student had allowed some oxidation of Fe(II) to Fe(III) to occur, would the absorbance reading be higher or lower than the true value? Explain your answer.
