And given that NH3 will absorb the shortest wavelength, NH3 would be Complex B. Therefore leaving Complexes A, C, and E which were also determined using the spectrochemical series. Complex A was -Cl , Complex C was -F and Complex E was determined as H2O . Final Conclusions: • In conclusion by using the data obtained in the second week’s experiment and the spectrochemical series the five cobalt complexes were determined as follows: 1. Complex A = -Cl 2. Complex B = NH3 3. Complex C = -F 4. Complex D = -Br 5. Complex E = H2O...
