Problem 80AE
Solutions of [Co(NH3)6]2+, [Co(H2O)6]2+ (both octahedral), and [CoCl4]2- (tetrahedral) are colored. One is pink, one is blue, and one is yellow. Based on the spectrochemical series and remembering that the energy splitting in tetrahedral complexes is normally much less than that in octahedral ones, assign a color to each complex.
