Question

The Fe(ox)33- ion forms an emerald green solution when it is dissolved. As stated in the Introduction section above, the crystal field splitting affects the color of the compound. In fact, compounds with different magnitudes of Δo will appear different colors, corresponding to the wavelength of light that enters our eyes. If the ion in solution appears emerald green to our eyes, what color of visible light is it mostly absorbing? What does that tell you about the magnitude of Δo (recall that E = hc/ƛ)? Determine if the complex is likely to be high spin or low spin based on this observation. Submit your answers on Sapling.
