A 1.0 cm cuvette contained a highly absorbing metal complex (ML).
a) 1.70 x 10-5 M ML was found to generate a detector response of 426 mV at 532 nm. When a non- absorbing species was placed into a 1.0 cm cuvette, the detector response measured was 765 mV at 532 nm. Calculate ε.
b) If the uncomplexed metal (Mn ) also absorbs weakly at 532 nm (with ε = 575 M-1 cm-1) what is the concentration of ML in a solution containing ML 0.0916 mM Mn if the detector response for the solution is 169 mV?
