Why is \(\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{6}\right]^{3+}\) diamagnetic while \(\left[\mathrm{CoF}_{6}\right]^{3-}\) is paramagnetic?
\(\mathrm{MnF}_{6}{ }^{2-}\) has a crystal field splitting energy, \(\Delta_{0}\) of \(2.60 \times 10^{2} \mathrm{~kJ} / \mathrm{mol}\). What is the wavelength responsible for this energy?
In the \(\mathrm{Ti}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}{ }^{3+}\) ion, the splitting between the \(\mathrm{d}\) levels, \(\Delta_{\mathrm{o}}\) is \(55 \mathrm{kcal} / \mathrm{mol}\). What is the color of this ion? Assume that the color results from a transition between upper and lower d levels.
What is the mass percent of chromium in the chloride salt of \(\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5}(\mathrm{OH})\right]^{2+} ?\)
Give the electronic configuration for (a) \(\mathrm{Ti}^{3+}\) (b) \(\mathrm{Cr}^{2+}\) (c) \(\mathrm{Ru}^{4+}\) (d) \(\mathrm{Pd}^{2+}\) (e) \(\mathrm{Mo}^{3+}\)
