Potassium permanganate, KMnO4, is a strong oxidizing agent and is reduced when it reacts. Here a circa 103M solution of potassium permanganate in a pipette is added to a beaker containing a primary alcohol (70% ethanol). Alcohol reduces violet Mn 7+ to nearly colourless Mn 2+. A dropperful of 1M NaOH has been added to the alcohol to promote a greater oxidation speed. | |
