Thus, the MnO 4-ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction. By giving up electrons, it reduces the MnO 4-ion to Mn 2+.. Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good Answer to: In an acidic solution, permanganate ion , MnO_4^-, reacts with Sn(II) ion to give Mn (II) ion and Sn(IV) ion, MnO_4^- + Sn^2+ ---> Mn^2+ PERMANGANATE ION 2BL953CCZ2 Overview Structure Names 6: Identifiers 5: Active Moiety 1: Notes 3: Audit Info References 8: Moieties 1: Substance Class: Chemical Record UNII: 2BL953CCZ2.

For the manganate ion MnO|4||2−|, see |Manganate|.

Permanganate crystals are nearly black, with a greenish violet hue, while permanganate solutions are usually tinted the red-violet color of the ion. Permanganates of sodium and bivalent metals dissolve freely in water, but KMnO4 is only sparingly soluble.

The permanganate ion acts as an oxidizing agent—it causes the oxidation of hydrogen peroxide. The oxidation half-reaction shows that two electrons are lost per molecule of hydrogen peroxide that is oxidized to oxygen gas (Equation 1).

Because manganese is in the +7 oxidation state, the permanganate (VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry. The permanganate ion (M n O 4 −) is a strong oxidant. The application is largely for aluminum and like many conversion coatings processes for this metal can be developed in alkaline or acidic solutions since Al is amphoteric 24; however, the best coating is achieved at elevated solution temperatures.
