Chapter 19, Problem 54E

Consider the complex ions ${\text{Co(NH}}_{\text{3}}{\text{)}}_{\text{6}}{}^{\text{3+}}{\text{, Co(CN)}}_{\text{6}}{}^{\text{3-}}{\text{, and CoF}}_{\text{6}}{}^{\text{3-}}$ . The wavelengths of absorbed electromagneticradiation for these compounds are (in no specific order)770 nm, 440 nm, and 290 nm. Match the complex ion tothe wavelength of absorbed electromagnetic radiation.
