Potassium permanganate, or potassium permanganate is a strong oxidant, therefore used for many synthesis treatments in the chemical industry. It has a violet colour. In addition to its oxidising properties, potassium permanganate is also used for its disinfectant properties and in deodorants. It generates strong exothermic reactions when mixed with many organic materials.

Some of the uses of potassium permanganate include:

  • Oxidising agent in many chemical reactions in the laboratory and industry.
  • In analytical chemistry, an aqueous solution of potassium permanganate is commonly used as an oxidising titrant in redox titrations because of its intense violet colour. When the aqueous potassium permanganate solution is in an acidic medium, the violet permanganate is reduced to the colourless Mn+2 cation. In neutral solutions, the permanganate is reduced to MnO2, cation +4, resulting in a brown precipitate. Finally, in alkaline or basic solutions, it is reduced to its +7 state, giving KMnO4, with the violet colour with which potassium permanganate is known.
  • It also has disinfectant and deodorant properties. It is used to treat some parasitic diseases of fish, or in the treatment of some skin conditions such as fungus or dermatosis. It can also be used as a remedy for some poisonings with oxidisable poisons such as elemental phosphorus or snakebites.
  • A common application is in the treatment of drinking water. In Africa, many people use it to soak vegetables in order to neutralise any bacteria that may be present.
  • Very dilute solutions of potassium permanganate can be used as a mouthwash (dilution of at least 0.15 %), and as a hand disinfectant (about 1.8 %).

6 reviews for Permanganato de Potasio


    It has fulfilled its function perfectly. I have used it to transform rusty areas of anchorages placed in outdoor areas, which sometimes got wet due to watering because of the wind.
