Potassium permanganate is an oxidizing agent that has an antiseptic and cauterizing effect. Potassium permanganate easily and quickly dissolves in warm water, coloring it bright colors(violet to light pink). The drug is used to treat many diseases. Potassium permanganate powder is diluted depending on the purpose: a weakly concentrated composition is prepared for oral administration, and for local application– stronger.

How to make potassium permanganate: general rules
To ensure that the solution is suitable, and the process of its preparation does not leave consequences in the form of burns on the skin and unwashable stains, you should adhere to some rules:
1. Use only glassware that is not used for food purposes.
2. Potassium permanganate, which is needed for treatment, is dissolved with warm boiled water.
3. Dry powder crystals burn the skin and leave indelible marks on it, so you need to take them not with your hands, but with a spoon, the tip of a knife or a cotton swab.
4. Water is first added to the solution container, and only then potassium permanganate.
5. The resulting product is stored in a cool, dark place. If possible, it is better to prepare a new composition before each use. Potassium permanganate stains strongly and is difficult to wash off, so it is best to avoid getting it on clothes or skin.
How to make a weak solution of potassium permanganate?
For washing the eyes, nose and throat, douching and baths, a concentration of 0.01−0.01% is required. To prepare such a solution, take 2-3 grains of potassium permanganate per glass of warm water. The result is a pale pink liquid.
To make a disinfectant composition, which is required for gastric lavage in case of poisoning, you need a solution of 0.02−0.1% (5−6 crystals per 200 ml of liquid).
The water turns red, but remains clear. To wash external wounds, a concentration of 0.1−0.5% is used (6−8 grains per glass of water). The product turns out to be a rich scarlet color, reminiscent of strong wine.
A 5% solution is a solution whose saturation is 5%. That is, the mass of dry matter, in in this case, potassium permanganate, should be 1/20 by weight of the solution.
You will need
- potassium permanganate, water, kettle, glassware
Instructions
1. First of all, you should know: never dissolve potassium permanganate in pots, ladles, basins or other kitchen utensils. Potassium permanganate will certainly leave its traces on them, and the material of the dishes may begin to react with the solution (do not forget, potassium permanganate is a salt, that is chemical compound, and behaves quite energetically in various environments). For our purposes, dishes made from clear glass, say, a liter can or juice bottle.
2. Now we have to correctly calculate the proportions. Most likely, you won’t have to weigh potassium permanganate for everyone: it is sold in packages on which the weight is clearly indicated - 5 g, 10 g, 15 g and so on. For every 5 grams of potassium permanganate, take 95 grams of water. That is, if we need 1 liter of a 5% solution, then we will need 10 packages of potassium permanganate, 5 grams each, and 950 grams of water.
3. Now the water should be heated: in warm water everything dissolves faster. Taking into account the fact that most likely everyone will need the solution for some medical or hygienic purposes, the optimal water temperature will be 35-40 degrees, this temperature can be easily determined with your fingers. The heated water is poured into a prepared clean jar, followed by potassium permanganate. You should not pour water into a dry substance - this is a general rule for preparing solutions. A glass rod is used for stirring in laboratories, but at home it is permissible to stir with a disposable plastic spoon; a metal one should not be used for this purpose.
Salt of manganese acid, potassium permanganate - all these are names of a common antiseptic, the one that is better known in everyday life as potassium permanganate. This chemical compound is often used in emergency treatment. medical care and treatment of various diseases, but it is necessary to prepare a solution of potassium permanganate correctly.
Instructions
1. When preparing a solution of potassium permanganate, take several crystals and, stirring, dissolve completely in a small amount of water. It is important to perform this procedure with metal or plastic objects that are resistant to staining and the effects of permanganic acid salts. Pour the resulting solution little by little into a vessel with clean water until the required concentration is obtained, which can be easily determined by the color of the liquid.
2. During gastric lavage caused by food poisoning toxic substances, use clear scarlet, but clear solution potassium permanganate, one to one and a half liters of which you need to drink. The special “chemical” taste of such a liquid will cause a gag reflex and will promote causeless emptying of the esophagus and intestines, and due to its antiseptic properties, they will be disinfected. It is important to ensure that when taking it, undissolved salt crystals do not accidentally get inside, which can lead to a burn to the gastric mucosa.
3. In order to stop diarrhea, prepare a pale pink solution of potassium permanganate and take a glass in the morning and evening. As usual, after a day of such therapy, the diarrhea stops.
4. To treat wounds, prepare a solution of permanganic acid, one that should have the color of thick red wine and treat the surface around the wound with it. The disinfecting effect of potassium permanganate will help protect the damaged area from the effects of pathogens.
5. To treat wounds resulting from the bites of poisonous snakes, use a concentrated ten percentage solution potassium permanganate, the one that has a purple color.
6. To prevent excessive sweating of the feet, prepare a pale pink solution of potassium permanganate. Baths with this solution will reduce sweat secretions. After each procedure, lubricate the skin with a one percent formaldehyde solution.
7. To treat bedsores, use a five percent solution of manganese salt and apply it once or twice a day to the affected areas.
Potassium permanganate or potassium permanganate is used in medicine to dry mucous membranes and skin, as well as for disinfection. However, preparing the solution requires great care.
Instructions
1. A solution of potassium permanganate is prescribed for poisoning. Once in the stomach, it has a disinfecting effect. This remedy is also used to gargle for scarlet fever and sore throat. Potassium permanganate is no less effective for sinusitis. In addition, the solution can be used to treat both surface and large wounds, for burns, sweating feet, damage to the oral mucosa, urological and gynecological diseases, as well as for hemorrhoids.
2. To lavage the stomach, make a 0.1% solution of potassium permanganate. Because the solution will be taken orally, for its preparation use only boiled water. Pour 1 gram of powder into a liter of water at a temperature of 37-38 degrees. Thoroughly mix the resulting liquid and strain it through three layers of gauze. The finished solution should have a purple tint, but be transparent. Make sure there are no undissolved crystals in the medicine, which could burn the stomach lining.
3. To treat a burn, prepare a more concentrated solution. Dissolve 2 grams of potassium permanganate in half a glass of water. As in the previous case, strain the resulting medicine. The solution is used externally cold, so cool it to room temperature before use.
4. Prepare a 5% solution for treating large wounds, particularly bedsores. To do this, pour a whole 5 gram package of potassium permanganate into 100 ml of water.
5. To wash your eyes, add a couple of potassium permanganate crystals to a glass of water. Even a pale pink solution has disinfecting properties, and therefore helps well with conjunctivitis. The same method is used to prepare medicine for douching for gynecological diseases.
Note!
Potassium permanganate has no contraindications, however, failure to follow the special technology for preparing the solution can lead to serious consequences.
Each of us knows about the unique antiseptic qualities of potassium permanganate, also called potassium permanganate. In most cases this medicine It is used only in low concentrations, for example, for preparing baths and rinses, as well as for gastric lavage. However, in some cases there is a need to prepare especially concentrated solutions of potassium permanganate, for example, one percent or five percent. Today we will talk about the second option of this medicinal composition– about how to make a 5 percent solution of potassium permanganate. Let's try to understand the intricacies of its preparation and use in as much detail as possible.
In general, potassium permanganate is a salt of permanganate acid; it appears as a powder consisting of tiny dark purple crystals that have a steel-blue luster. Potassium permanganate dissolves well in water, resulting in a liquid of different colors. Weakly concentrated solutions are pinkish in color, while highly concentrated solutions are purple, almost black.
Potassium permanganate is a fairly strong oxidizing agent; accordingly, it has a pronounced antimicrobial (antiseptic) effect. This effect is explained by the fact that in an aqueous solution, in the presence of easily oxidized elements, gaseous oxygen is actively split off from potassium permanganate, and it is very strong antiseptic.
After this, poorly soluble brown manganese oxide remains.
In significant concentrations, potassium permanganate has a pronounced irritating and cauterizing effect.
Application of a five percent solution of potassium permanganate
This version of the potassium permanganate solution is considered particularly concentrated. Under no circumstances should it be used for treating mucous membranes or for internal consumption, since this use will cause severe burns.
Such a concentrated solution can only be used externally and in extreme cases. So, some experts advise applying it to areas affected by fungal diseases - on the skin (not on mucous membranes) and on nails. However, mycologists claim that the use of special antifungal drugs will be much more effective and safe.
There is confidence that the use of a five percent solution of potassium permanganate will help cope with the poison from the bites of poisonous snakes, scorpions and tarantulas. In this case, this product is used to wash the affected areas. But it must be borne in mind that such first aid does not at all eliminate the need to call an ambulance and immediate hospitalization (if necessary).
Some experts traditional medicine claim that a strong cold solution of potassium permanganate can be used to treat thermal burns. In this case, the product is used cold, preparing lotions on the affected areas based on it. But effectiveness and safety this treatment It is strongly recommended to discuss with your doctor.
Similar recommendations apply to advice on the treatment of bedsores using a five percent solution of potassium permanganate. They claim that this remedy effectively prevents the appearance of such unpleasant and dangerous formations. To prevent bedsores, it is recommended to wipe areas of the body that are dangerous from this point of view, using a solution of potassium permanganate.
Also, a concentrated five percent solution will also help in the treatment of various types of generalized skin lesions, for example, pyoderma or chickenpox. In order to speed up the drying and falling off of the crusts a little, patients will benefit from baths with the addition of potassium permanganate. First, you need to make a concentrated solution in a separate glass container, after which you need to pour it into a warm bath, until the water turns into pink tones. The duration of this procedure is no more than a quarter of an hour. After it, the patient should be doused with slightly cooler clean water. Baths can be repeated every day.
A five percent solution of potassium permanganate can be used as an effective cauterizing agent. This way you can try to remove warts or calluses. This remedy can also be applied to acne, for example, on the back, but only pointwise.
How to prepare a 5 percent solution of potassium permanganate?
It is best, of course, to use precise scales to prepare a solution of potassium permanganate. In this case, creating such a tool will not be difficult for you. Just dilute five grams of crystals in one hundred milliliters of water.
If you don’t have scales at hand, then the situation is somewhat more complicated. But nothing is impossible. As you know, an ordinary teaspoon with a volume of five milliliters contains six grams of potassium permanganate. Accordingly, to prepare a five percent solution, you should combine this volume of potassium permanganate with one hundred and twenty milliliters of water.
If you purchased a bottle of potassium permanganate with a volume of three grams at the pharmacy, then to prepare a five percent solution you need to combine it with seventy milliliters of water.
After all the potassium permanganate crystals have dissolved in water, pass the resulting solution through gauze folded in several layers. This will prevent possible burns from undissolved chemical particles.
Etching with potassium permanganate- the simplest and most common method of seed disinfection. At the same time, it is very effective, since of all chemical etchants, potassium permanganate has the most wide range actions.
However, dressing with potassium permanganate does not guarantee complete disinfection: while reliably killing infectious agents on the surface of the seeds, it is powerless to influence the infection nesting inside the seed.
Seeds are treated with a 1% or 2% KMP04 solution. Optimal modes treatments for different seeds are not the same.
Seed treatment modes with potassium permanganate
- Celery, onions, tomatoes, physalis, lettuce, radishes, corn, beans, peas, beans; 1% solution of KMn04, 45 min.
- Peppers, eggplants, cabbage, parsnips, carrots, dill, pumpkin crops: 2% solution of KMn04, 20 min.
- Seed treatment is carried out at room temperature, followed by washing with tap water.
- To prepare a 1% solution, 1 g of potassium permanganate is dissolved in 100 ml (1/2 cup) of water, to prepare a 2% solution - 2 g in 100 ml of water.
To be able to weigh small amounts of chemicals, you need to make simple scales from scrap materials. Working by eye in such an important matter as seed dressing can have dire consequences. Here you cannot make a mistake either in the direction of increasing or decreasing the concentration. Without weighing, measuring potassium permanganate by volume, you can also prepare a solution with sufficient accuracy. For this you need a standard (5 ml volume) teaspoon. One level teaspoon contains 6 g of potassium permanganate. "No top" means that excess material is skimmed off with the flat side of the knife.
How to prepare a solution of potassium permanganate without weighing?
2% solution of KMn04: Dilute one level teaspoon in 300 ml (one and a half glasses) of water.
1% solution of KMn04: Pour out part of the 2% solution of potassium permanganate and add an equal volume of water to it; or dilute one level teaspoon in 600 ml (in three glasses) of water.
The resulting solutions have a thick, almost black color. Treating seeds with less concentrated solutions (pink, dark pink or purple when the bottom is visible through the solution) does not provide disinfection.
Disinfection does not occur in cases where stuck together seeds are processed. Tomato seeds are especially prone to sticking together. Before immersing them in potassium permanganate, they need to be rubbed with your hands so that each seed is moistened on all sides. For tomatoes, heating is much more reliable than pickling.

Dark crystals Potassium permanganate is still present in many first aid kits, despite the fact that the sale of this product has long been discontinued.
The pharmacy offers a huge selection of other different medications for all occasions. However, the powder and water solution Potassium permanganate for treating wounds is still suitable for use.
In what cases can potassium permanganate be used?
Crystals of potassium permanganate or potassium permanganate (KMnO 4) are potassium salt manganese acid. The powder is dark burgundy, almost black in color, highly soluble in water, and is a strong oxidizing agent. Upon contact with living skin cells in solution or pure form atomic oxygen is released, due to this the appearance of antiseptic properties drug.
Indications:
Potassium permanganate should not be used if you are hypersensitive to potassium and magnesium.
In case of an overdose, pain occurs in the oral cavity, swelling of the mucous membrane of the esophagus, pharynx, abdominal pain, vomiting, diarrhea, and burn shock is possible. To ensure that treatment with the drug does not lead to dire consequences or cause complications, the powder must be properly diluted with potassium permanganate to treat the wound and the dosage must not be exceeded.
How to properly dilute potassium permanganate for treating wounds
To dissolve salt crystals, it is better to use warm water, so the powder will dissolve faster. To dilute, the water should be boiled, then cooled to about 40 O C. For 1 liter of liquid you need to take a pinch of potassium permanganate.
To properly prepare a solution of potassium permanganate for treating wounds, you need to know:
- Do not handle the substance with bare hands, as this can cause severe skin burns. For this purpose, use a spoon, knife, or flat wooden stick;
- The finished solution should be light raspberry in color. If the result is a darker concentration, then to treat wounds, the solution of potassium permanganate must be diluted with water until the desired shade is obtained;
- Undissolved particles settle at the bottom of the container; you need to wait a little for them to dissolve, or the liquid must be filtered through several layers of gauze or a fine sieve;
- The finished product must be used immediately after preparation, since it cannot be stored; the remaining drug is poured out.
Potassium permanganate, dissolved in water, has a disinfecting and eavesdropping effect. The solution is widely used in dermatology, surgery, gynecology, and urology.
In surgical practice, the liquid is used to treat wounds, and dried bandages are also soaked in the solution to make a dressing.
To lavage the stomach, it is not necessary to use a tube; the patient simply drinks 0.5-1.5 liters of light pink liquid, after which vomiting is caused by a reflex when pressing on the root of the tongue. In case of poisoning with alcohol, morphine, medicines, when vomiting needs to be induced immediately, patients are also given potassium permanganate to drink.
Proper use of the solution
In everyday life, potassium permanganate is used to remove pain for calluses, foot baths are used for this. In a bowl of water, also add a tablespoon of table salt or baking soda. The legs are lowered into the basin for 15 minutes, after a while the calluses stop hurting.
