    Permanganate reacts with concentrated hydrochloric acid to give chlorine and manganese(II): 2 KMnO 4 + 16 HCl → 2 MnCl 2 + 5 Cl 2 + 2 KCl + 8 H 2 O. In neutral solution, permanganate slowly reduces to manganese dioxide (MnO 2). This is the material that stains one's skin when handling KMnO 4. KMnO 4 reduces in alkaline solution to give green ...

    en.wikipedia.org/wiki/Manganese

    Manganese(IV) oxide (manganese dioxide, MnO 2) is used as a reagent in organic chemistry for the oxidation of benzylic alcohols (where the hydroxyl group is adjacent to an aromatic ring). Manganese dioxide has been used since antiquity to oxidize and neutralize the greenish tinge in glass from trace amounts of iron contamination. [ 45 ]
