Sketch the general shape/appearance of a "spectrophotometric titration curve" for the following system. You should label the axes of the graph, and show an approximate numeric scale (including units) on both axes. 50.0 mL of 0.000100 M Fe"(phen)^2+_3 (aq) + 0.01000 M Ce^4+ (aq) rightarrow Fe"'(phen)^3+_3 (aq) + Ce^3+ (aq) The substance being titrated, Fe"(phen)^2+_3, has epsilon = 12, 100 M^-1cm^-1 at the wavelength of 510 nm that was used. During the course of the spectrophotometric titration, the absorbance of the solution is measured in 1.00 cm cells. The titrant Ce^4+, as well as the products Fe"(phen)^3+_3 and Ce^3+ are all colorless at 510 nm (you may assume that epsilon = 0 M^-1cm^-1).
