Oxidation States of Manganese.docx - Oxidation …

Oxidation States of Manganese Manganese readily forms compounds over a range of oxidation states that is wider than that of any other common metal. Figure 20.8 shows the relative stabilities for the oxidation states of manganese in acid solution. From this diagram, we can see that the permanganate ion, [MnO 4] 2, also called tetraoxidomanganate(VII), is very strongly oxidizing in acid solution.
