Results and Discussion: Cobalt Complex A was synthesized and purified chemical reactions and vacuum filtration. The wavelengths of maximum absorbance in the visible spectrum of five cobalt complexes were measured and recorded as shown in the following table: Complex A B C D E Wavelength (nm) 530.20 475.44 513.01 547.62 484.70 Using the inverse relationship between the crystal field splitting (

Unformatted text preview: ∆ ) and wavelength ( λ ) in ∆ = h ν = hc/ λ , and the spectrochemical series: Br < Cl < F < H2O < NH3 , the identity of each complex was determined. Conclusion: The identity of: Complex A is Co(NH 3 ) 5 Cl 2 Complex B is Co(NH 3 ) 5 NH 3 3 Complex C is Co(NH 3 ) 5 F 2 Complex D is Co(NH 3 ) 5 Br 2 Complex E is Co(NH 3 ) 5 H 2 O 3 ....
