What Is Potassium Permanganate Used For?

From medication to chemical manufacturing, potassium permanganate has numerous makes use of and functions. Its antiseptic properties make it an important medication that’s usually used to deal with wounds and pores and skin circumstances, akin to dermatitis. 

Alongside its medicinal functions, potassium permanganate is used to deal with water and protect meals. Chemical manufacturing firms and laboratories additionally use it as an oxidising agent.

With such a various vary of functions, potassium permanganate is likely one of the most essential chemical substances available on the market.

How do you employ potassium permanganate?

You should utilize potassium permanganate in a number of methods, relying in your necessities. For instance, you should utilize it as medication when you’ve got dermatitis. Alternatively, in case you’re a chemistry pupil or skilled chemist, you should utilize it in laboratory evaluation and as a reagent in synthesising natural compounds.


Potassium permanganate has been a part of frequent medication for the reason that 1800s, and is at the moment included within the World Well being Organisation’s Listing of Important Medicines. It may be used to deal with all kinds of pores and skin circumstances, together with:

  • Fungal foot infections
  • ImpetigoMale hand with impetigoPotassium permanganate can be utilized to deal with impetigo
  • Pemphigus
  • Superficial wounds
  • Dermatitis
  • Tropical ulcers

When treating pores and skin circumstances, potassium permanganate can both be used alone as an answer, or along with different substances.

For instance, it’s mixed with procaine benzylpenicillin to deal with tropical ulcers. It’s significantly efficient at treating pores and skin illnesses that produce quite a lot of liquid. A dressing soaked in an answer of potassium permanganate is normally utilized to the affected space or it may be used as a shower.

Water therapy

The water therapy business makes use of potassium permanganate to take away dissolved iron and hydrogen sulphide from water in wells. These substances trigger water to odor, so utilizing potassium permanganate helps to eliminate the ‘aroma’ of rotten eggs. That is finished by means of a ‘Manganese Greensand’ Filter.

Potassium permanganate can also be used to regulate the proliferation of pesky freshwater organisms in water assortment and therapy amenities.

Natural compound synthesis

Chemical manufacturing and pharmaceutical firms use potassium permanganate to synthesise natural compounds.

Among the essential natural compounds which are industrially synthesised utilizing potassium permanganate embrace:

  • Ascorbic acid – often known as vitamin C, ascorbic acid is an antioxidant that may be added to drinks
  • Chloramphenicol – an antibiotic that’s used to deal with numerous infections, like conjunctivitis and cholera
  • Saccharin – a man-made sweetener extensively utilized by diabetic sufferers
  • Isonicotinic acid – an isomer of nicotinic acid (vitamin B3)
  • Pyrazinoic acid – used to deal with tuberculosis, significantly resistant strains of Mycobacterium tuberculosis

Laboratory evaluation

As a powerful oxidising agent, potassium permanganate performs a key position in analytical chemistry. A chemist holds test tube of glass containing a liquid solution of potassium permanganate while conducting an analysis of water samples.

For instance, it may be used to quantitatively decide the full quantity of natural materials that may be oxidised in an aqueous resolution. Generally known as the permanganate worth, it’s a great tool to ascertain the extent of natural air pollution in a physique of water.

Preserving fruits

Fruits ripen and ultimately rot when ethylene is launched. Nonetheless, potassium permanganate can successfully take in and oxidise ethylene, thus slowing down the ripening course of. This makes it attainable to increase the shelf lifetime of fruits to as much as 4 weeks with out the necessity for refrigeration. 

What does potassium permanganate do?

The varied functions of potassium permanganate primarily depend on the compound’s sturdy oxidising properties. Its skill to oxidise natural substances, together with microorganisms, is the explanation why it may be used as an antiseptic and disinfectant.

This identical property makes it helpful in synthesising natural compounds and analysing the amount of natural compounds in aqueous options.

Is potassium permanganate dangerous?

At greater concentrations, potassium permanganate can irritate the pores and skin and go away long-lasting stains.

Being a powerful oxidising agent means potassium permanganate can take away electrons from a molecule. This breaks the bonds between the constituent atoms, which has dangerous results on dwelling cells. 

When ingested, potassium permanganate can injury the higher gastrointestinal tract and should trigger bleeding. The deadly dose of potassium permanganate to an grownup human is about 10 grams.

Getting ready potassium permanganate resolution

The way you put together an answer of potassium permanganate is determined by the aim of the answer.

For example, if you wish to make a standardised resolution of the substance, you should weigh the crystals primarily based on the molar mass and dissolve them in a typical proportional quantity of water. This is able to provide the desired focus.

Within the following instance, we present the right way to put together a 0.02 M aqueous resolution of potassium permanganate.

  1. Dissolve 3.2 grams of potassium permanganate in 1 L of distilled water. That is the equal of two% of the molar mass of the substance, which is 158.034 g/mol
  2. Warmth a water tub for one hour
  3. Enable the setup to accept two days
  4. Filter by means of glass wool
  5. Standardise the answer

Can I purchase potassium permanganate over-the-counter?

Pharmacies usually promote potassium permanganate as an over-the-counter treatment for pores and skin circumstances. It’s usually offered as a fungicidal product in pill type. It may also be dissolved in water for bathing.

The place to purchase potassium permanganate 

You should buy potassium permanganate out of your native pharmacy. You can even purchase it on-line from a good chemical producer, both in bulk or retail volumes. You usually should be a enterprise to purchase it on this method. ReAgent's 25l bottle of potassium permanganate
