REPORT: EXPERIMENT M – SPECTROPHOMETRIC
DETERMINATION OF IRON
Name ___________________________________
Laboratory Section _________Date ___________
Laboratory Instructor ______________________
Part I: Standard Solutions
1.
Calculate the concentration of the four [Fe(Bipy)3]
2+
complex standard solutions prepared
in Part I. The relation, C1V1 = C2V2, may be used. (1.0 marks)
Part II: Absorption Spectra for the [Fe(Bipy)3]
2+
complex
1.
Plot the absorption spectra for the [Fe(Bipy)3]
2+
complex in the visible region of the
electromagnetic spectrum by drawing a graph of absorbance versus wavelength using
your experimental data. Use graph paper with a 1.0 mm grid. Label each axis clearly
and title the graph appropriately. Include the graph with your report. (1.0 mark)
2.
Record the wavelength of maximum absorption in the visible region (
max
) for the
[Fe(Bipy)3]
2+
complex. (0.2 marks)
