Unformatted text preview: Co(NH 3 ) 6 . Complex C had the third highest crystal field splitting and was therefore identified as Co(NH 3 ) 5 F-. Complex D, with it lowest crystal field splitting, was identified as Co(NH 3 ) 5 Br-. Lastly, Complex E was identified as Co(NH 3 ) 5 (H 2 0). This was all based on this spectrochemical series (where the crystal field splitting increases from left to right): Br-<Cl-<F-<H 2 O<NH 3 Conclusion : Each of the five cobalt complexes was identified after using their maximum absorbed wavelengths to calculate their crystal field splitting. Our cobalt complex, complex A, was identified as Co(NH 3 ) 5 Cl- and cobalt complex B was identified as Co(NH 3 ) 6 ....
