Unformatted text preview: should be used to report your "column-separated" answer. Cobalt Standardization Curves Provide the Molar Absorptivities: from 470 nm data from 518 nm data The concentration obtained from the higher molar absorptivitiy is the most reliable and CoL 2 NiL 2 λ =470 nm λ =518 nm M-1 cm-1 at 470 nm M-1 cm-1 at 518 nm Calculate [Ni 2+ ] in solution #9 from each of the the working curves: M-1 cm-1 at 470 nm M-1 cm-1 at 518 nm Calculate [Co 2+ ] in solution #10 from each of the the working curves: should be used to report your "column-separated" answer....
