Given that the observed absorption maximum for the complex ion CoF₆^3-in solution is $\Delta$_max = 700 nm, what is the value of the crystal field splitting,$\Delta$o ?

Question

Quizplus · Accepted Answer

The crystal field splitting energy, $\Delta_o$, can be calculated using the formula $\Delta_o = hc/\lambda$, where $h$ is Planck's constant ($6.626 \times 10^{-34} \, \text{J s}$), $c$ is the speed of light ($3.00 \times 10^8 \, \text{m/s}$), and $\lambda$ is the wavelength of light absorbed ($700 \, \text{nm} = 700 \times 10^{-9} \, \text{m}$). Substituting these values into the formula gives a $\Delta_o$ value in the order of magnitude of $10^{-19} \, \text{J}$, which corresponds to choice A.
