A and B form complexes with H,O, that absorb in the visible portion of the electromagnetic spectrum. A sample containing both A and B was treated with excess H,O, and the UV-Vis spectrum was measured. UV- Vis spectra were also obtained for standard solutions treated with excess H,O, which only contained one or the other of the metal ions. The absorbance values measured at two wavelengths for each of the solutions are summarized in the table below. Calculate the concentration of both A and Bin the unknown solution. Remember to show any relevant work or equations. Absorbance Absorbance [A] [B] (410nm) (460 nm) 1.32 mM O mM 0.96 0.55 O mM 1.89 mM 0.43 0.52 unknown unknown 0.74 0.59
