Potassium permanganate(KMnO4) is coloredbecause it absorbs light in the visible range of the electromagnetic spectrum. The permanganate ion is the source of the color, as a ligand-to-metal charge transfer takes place between the oxygen's p orbitals and the empty d-orbitals on the metal. What ...
There are also other oxidants that can be used for this purpose, such as chromium dioxide or potassium permanganate, but they usually need multiple steps, first convert the Philippines into Philippines, and then convert them into Diphenic Acid. 6. Treatment and storage (1) Precautions for operat...
