6, 7, and 8 mL.)
3. With the proper technique measure the absorbance of each of these solutions at the
wavelengths you determined above for the absorption maxima of both the red and the
green complexes (for a total of 8 readings).
4. One test tube at a time, repeat steps 2 and 3 with the four samples of the green
complex. As before, you can use the diluted samples immediately unless water vapor
condenses on the outside of the test tube after mixing--in which case warm it up with
5. When you are finished with Part III, you should have collected a total of 16 different
absorbance readings here; 8 for the red solutions and 8 for the green solutions.
Part IV. Collecting Data for the Analysis of a Mixture of the Two Complexes. Your TA will give you a solution that contains a mixture of the red and green complexes
prepared by allowing a solution of the chloro complex to partially convert to the aquo
product. Measure the absorbance of the mixture at the wavelength of maximum
absorbance found for green solution in Part I and measure the absorb...
