Step-by-Step Solution:

Step 1 of 5) The permanganate ion strongly absorbs visible light, with a maximum absorption at 565 nm. Because violet is complementary to yellow, this strong absorption in the yellow portion of the visible spectrum is responsible for the violet color of salts and solutions of the ion. What is happening during this absorption of light The MnO4 - ion is a complex of Mn(VII). Because Mn(VII) has a [Ar]3d0 electron configuration, the absorption cannot be due to a d-d transition because there are no d electrons to excite! That does not mean, however, that the d orbitals are not involved in the transition. The excitation in the MnO4 - ion is due to a charge-transfer transition, in which an electron on one oxygen ligand is excited into a vacant d orbital on the Mn ion (Figure 23.36). In essence, an electron is transferred from a ligand to the metal, so this transition is called a ligand to-metal charge-transfer (LMCT) transition. An LMCT transition is also responsible for the color of the CrO4 2-, which contains the Cr(VI) ion with an [Ar]3d0 electron configuration.
