A little about what potassium permanganate is

Hi all!

I continue to talk about such a well-known substance as potassium permanganate. I have already figured out why it is often difficult to buy and what restrictions there are for selling. Now I propose to go directly to the substance itself and see what it is.

So, chemists call this substance potassium permanganate.

Other names:

• potassium permanganate,
• potassium permanganate,
• kalii permanganas (in Latin).

It is incorrect to say "manganese". It's like calling a brick silicon.

Manganese in its pure form is a metal, and in permanganate it exists as a manganese atom combined with one potassium atom and four oxygen atoms. The formula of permanganate is written KMnO4.

Pharmacodynamics and pharmacokinetics

Potassium permanganate - what is it?

Potassium permanganate or potassium permanganate is potassium permanganate. The drug has the form of fine powder (crystals) of red or dark purple color with a metallic sheen. The substance dissolves in water in a ratio of 1:18, a weak aqueous solution is pinkish, a concentrated solution is dark purple.

Pharmacodynamics

Antiseptic . When potassium permanganate (potassium permanganate) comes into contact with organic substances, atomic oxygen is formed.

The oxide that is formed during the reduction of the drug forms complex compounds with proteins - albuminates . Due to this, potassium permanganate in small concentrations has astringent properties, and in concentrated solutions it exhibits a cauterizing, irritating and tanning effect.

Shows deodorizing properties . Effective in treating ulcers and burns.

Potassium permanganate has the ability to neutralize certain poisons, and this property is often used in situations where it is necessary to perform gastric lavage in case of foodborne illnesses and poisoning with unknown substances.

Pharmacokinetics

If ingested, it is absorbed and can cause the development of methemoglobinemia (hematotoxic effect).

What does he look like

These are dark purple crystals, so dark that they even appear black. Under no circumstances should they be touched with your hands to avoid getting burned. In addition, brown marks that are difficult to wash off will remain on the skin.

It dissolves well in water, and if the water is warm, dissolution occurs faster.

Even one crystal gives a pink color. The more you dissolve this substance, the richer the color will be - from light pink to dark purple.

Indications for use of potassium permanganate: why is potassium permanganate needed?

Aqueous solutions with a concentration of about 0.1% are used as an antiseptic

The product is used for treating burned areas of the body, for washing ulcers and infected wounds, for rinsing the oropharynx and throat in infectious and inflammatory diseases of the oral mucosa and oropharynx (including sore throat phenylamine ( aniline) comes into contact with it ) and eyes if they are damaged by poisonous insects.

As an emetic, potassium permanganate is taken orally for poisoning with alkaloids (for example, aconitine, morphine or nicotine), quinine, phosphorus, hydrocyanic acid. The optimal concentration of potassium permanganate solution for poisoning is 0.02-1%.

A solution for bathing a newborn is prepared with the addition of potassium permanganate.

Is it possible to wash with a solution of Potassium Permanganate?

Douching with potassium permanganate in gynecology is sometimes used for inflammatory processes and thrush .

Men with thrush and a number of urological diseases are recommended to wash with potassium permanganate.

Douching for thrush is carried out with a slightly pink solution (concentration not higher than 0.1%). It should be remembered that a remedy such as potassium permanganate gives a short-term antimicrobial effect (pathogenic flora is destroyed only during the procedure), so it should be used only as an addition to the main treatment.

Crystals of the drug tend not to dissolve immediately. In this regard, in order not to cause a burn to the genital mucosa, the solution for washing/douching is prepared as follows: first, a concentrated (bright crimson) solution is made in a separate container, and then it is gradually poured into boiled water.

Potassium permanganate for diarrhea

An aqueous solution of potassium permanganate is often used in folk medicine to treat diarrhea. For diarrhea , adults usually take the drug orally, while children (including infants) are often given an enema with potassium permanganate.

For diarrhea, several crystals of potassium permanganate are dissolved in a glass of water, and then the resulting solution is poured into another container of water. A single dose for an adult is 200 ml, for a child - 100 ml. In some cases, to stop diarrhea, it is enough to take 1 single dose of the medicine.

Potassium permanganate is a salt of permanganate acid. Its effectiveness against vomiting and diarrhea is due to the high oxidizing ability of the permanganate ion, which provides the antiseptic effect of the product.

Potassium permanganate for hemorrhoids

For hemorrhoids , baths, lotions and washing with potassium permanganate help reduce swelling , burning and pain in the rectal area, thereby significantly alleviating the patient's condition.

To prepare a bath for hemorrhoids , use 1.5 tbsp. Dilute tablespoons of dry potassium permanganate powder in 10 liters of warm water. The indicated proportions are relative.

First of all, it is recommended to focus on the color of the finished solution: the liquid should be soft pink, not bright. A solution that is too concentrated can cause a chemical burn to already inflamed and sensitive skin.

The duration of the procedure is 15 minutes. To achieve a lasting effect, you need to repeat it 2-3 times a day. Treatment is continued until improvement is noticeable.

If it is not possible to make a bath, the same result can be obtained using lotions (applications) with potassium permanganate.

The solution can also be used for regular anal hygiene. Treatment usually lasts about 1 week.

Octenidine (octenidine dihydrochloride)

A cationic surfactant with antimicrobial activity against gram-positive and gram-negative bacteria, viruses, as well as against yeast-like fungi and dermatophytes (fungi that feed on keratin and cause dermatomycosis). Similar in action to quaternary ammonium compounds (QAC). The damaged surface is completely processed. Can be used on mucous membranes. The antiseptic has no age restrictions and is used for children. Currently, it is the drug of choice in Europe as an antiseptic due to its wide spectrum of action and maximum speed of achieving effect.

Potassium Permanganate: instructions for use (Method and dosage)

According to the instructions for use, the product is applied externally, in the form of aqueous solutions of various concentrations:

• 0.02-1% - for gastric lavage in case of poisoning, douching and washing;
• 0.01-1% - for gargling and mouth;
• 0.1-05% solution - for treating wounds;
• 2-5% - for lubricating burn and ulcer surfaces.

The use of concentrated solutions of potassium permanganate

A five percent solution of potassium permanganate is considered particularly concentrated, so it cannot under any circumstances be used for internal consumption and treatment of mucous membranes: the product is used only in extreme cases and only externally.

Some experts recommend its use to treat fungal skin infections and onychomycosis , but most mycologists prefer to prescribe specific antifungal drugs , which they believe are safer and more effective.

There is also an opinion that a 5% solution is effective against bites of poisonous insects (for example, tarantulas or scorpions) and poisonous snakes. In this case, it is used to wash the affected area, however, such a measure can only be regarded as first aid to the victim, and does not eliminate the need to see a doctor and immediate (if necessary) hospitalization.

In folk medicine, lotions with a concentrated cold (!) solution of potassium permanganate are sometimes used to treat thermal burns . It is also believed that regular treatment of areas of the body that are dangerous from the point of view of the occurrence of bedsores with a strong solution of potassium permanganate helps prevent degenerative or ulcerative-necrotic changes in tissue .

The safety and effectiveness of such treatment, however, should always be discussed with your doctor.

A five percent solution is also used to treat generalized skin lesions , such as pyoderma .

An acne bath with potassium permanganate helps accelerate the drying of the rash elements and the falling off of the crusts. The procedure is repeated daily until the manifestations of the disease disappear. The duration of exposure is no more than 15 minutes. After a bath, it is recommended to rinse your skin with cool water.

The concentrated solution can be used for acne on the back, as well as for cauterization of calluses and warts . In these cases, the product is applied pointwise.

How to dilute potassium permanganate for chickenpox?

For chickenpox , potassium permanganate is diluted so that the solution is not too concentrated. This means that the liquid should be light pink in color.

The dilution rules are as follows: first, a few grains of potassium permanganate are dissolved in about 500 ml of warm water, and then the resulting solution is poured into another container and the volume of water is adjusted to the required volume.

Use a cotton swab replaced in the solution to wipe the rash areas. When the rashes go away, to speed up the drying process of the crusts, you can take baths with a non-concentrated solution of potassium permanganate.

How to make a 5% solution of potassium permanganate?

To prepare a 5% solution, 5 grams of the drug are dissolved in 100 ml of water. To avoid mistakes with the dosage, you must use a kitchen scale.

If there are no scales, when calculating the required amount of potassium permanganate, it is based on the fact that 1 teaspoon contains 6 grams. Thus, to obtain a 5% solution, add this amount of potassium permanganate to 120 ml of water.

If a 3-gram bottle of potassium permanganate was purchased at the pharmacy, potassium permanganate should be combined with 60 ml of water to obtain a solution of the required concentration.

When all the crystals dissolve in water, the finished solution is filtered through gauze folded in several layers.

How to breed potassium permanganate for bathing a newborn?

Because babies' skin is very delicate and sensitive, a light pink, non-concentrated bath solution should be used for bathing.

Recommendations on how to make a weak solution of potassium permanganate are as follows: pour warm water into a transparent glass container and add a small amount of potassium permanganate (at the tip of a knife).

After making sure that all the crystals have dissolved, the solution is poured into another container and water is added to the required volume.

Interaction

Potassium permanganate is chemically incompatible with a number of organic substances (including tannin, sugar, coal).

Explodes when treated with concentrated H2SO4 (sulfuric acid).

Even with slight heating (to room temperature) it actively interacts with most reducing agents (for example, glycerin ) and easily oxidized substances. The reaction is accompanied by self-heating, which in some cases causes self-igniting mixtures and can lead to an explosion.

It is very dangerous to grind crystals of potassium permanganate with powders of active metals and non-metals (aluminum, sulfur, calcium, phosphorus, magnesium, etc.), since such actions are often accompanied by an explosion.

Properties

Potassium permanganate is a crystalline powder with shiny crystals of purple, almost black color, odorless. Water-soluble, in addition, it dissolves well in methyl alcohol, acetone, liquid ammonia, pyridine. The aqueous solution has a characteristic color, the color depends on the concentration - from slightly pink to raspberry-lilac and dark purple. The aqueous solution has a weak but unpleasant odor. The aqueous solution gradually decomposes in the light, so it must be stored in the dark or in dark glass containers. When heated, the crystals decompose, releasing oxygen; this method is used in laboratories to produce O2.

Potassium permanganate is a very strong oxidizing agent. Reacts actively with organic and inorganic acids, even to the point of explosion. Interaction with chemically active reagents in powder form (aluminum, magnesium, calcium, sulfur, phosphorus) can lead to self-ignition and explosion. Reacts violently with flammable chemicals, many organic substances (glycerin, sucrose, tannins, etc.) - an exothermic reaction begins, which can also end in an explosion.

Potassium permanganate - what is it?

Wikipedia states that potassium permanganate, which is more often called potassium permanganate in everyday life, is the potassium salt of permanganate acid, a strong inorganic acid, which has the formula HMnO4.

Everyone knows what potassium permanganate looks like - everyone has seen dark purple crystals with a metallic sheen at least once in their life.

Properties and uses of potassium permanganate in medicine

Potassium permanganate is a strong oxidizing agent and, therefore, has a pronounced antiseptic (antimicrobial) effect .

The effects of the product are explained by the fact that in an aqueous solution, in the presence of easily oxidized elements, gaseous oxygen begins to be actively split off from potassium permanganate, which exhibits the properties of a very powerful antiseptic .

In concentrated solutions, potassium permanganate has a pronounced cauterizing and irritating effect.

What can be made from Potassium Permanganate: alternative uses

In addition to medicine, the product is used:

• to determine permanganate oxidation when assessing water quality using the Kubel method;
• for washing laboratory glassware (an alkaline solution of potassium permanganate removes residues of fat and other organic substances well);
• in pyrotechnics (as a strong oxidizing agent);
• for toning photographs (solutions with a potassium permanganate concentration of 3 g/l);
• in space liquid-propellant rocket engines (as a catalyst for the decomposition of hydrogen peroxide);
• for etching wood;
• for removing tattoos (however, this method does not completely remove the tattoo and leaves scars on the body);
• for the production of carboxylic acids from paraffins;
• for bleaching fabrics.

On the Internet you can find a video “Potassium permanganate and gasoline”, in which potassium permanganate is recommended to be added to a car’s gas tank to enrich the fuel with oxygen.

Chemical properties

The formula of potassium permanganate is KMnO4. Molar mass - 158.03 g/mol. The substance has the form of dark purple crystals, does not form crystal hydrates, is characterized by moderate solubility in water (solubility increases with increasing water temperature), does not hydrolyze, and decomposes slowly in solutions.

Strong oxidizing agent during sintering and in solution. Reacts with typical reducing agents (hydrogen, ethanol, etc.). Concentrated solutions have an intense violet color, weak solutions are pink.

The oxidizing ability of the permanganate ion weakens as the acidity of the solution decreases. In an alkaline environment, under the influence of reducing agents, it is reduced to manganate ion; MnO4 in slightly alkaline, neutral and slightly acidic environments transforms into manganese dioxide.

In an acidic environment, the permanganate ion is transformed into an aquacation.

The equivalence factor of potassium permanganate feq(KMnO4) depending on the acidity of the medium is 1/5, ⅓ and 1.

A diluted aqueous solution of potassium permanganate is unstable and decomposes with the formation of a precipitate of manganese dioxide (brown flakes) and the release of oxygen. Decomposition is accelerated by exposure to sunlight.

A solution of potassium permanganate deteriorates especially quickly in the presence of reducing agents.

The acidified solution becomes discolored under the influence of oxalic acid solution. It is also used in titrimetric analysis for the determination of hydrogen peroxide, iron (II) salts, and oxalates.

The hydrocarbon does not discolor the potassium permanganate solution (acidified). Benzene does not discolor a solution of potassium permanganate. Discoloration is caused by passing hydrogen sulfide through an acidified solution of KMnO4.

Ethylene discolors a solution of potassium permanganate when passed through it (as ethylene oxidizes to ethylene glycol).

The oxidation reaction of ethylene with potassium permanganate looks like this:

During this reaction, the purple color of an aqueous solution of potassium permanganate discolors, so it is used as a qualitative reaction for alkenes.

A dilute solution of KMnO4 in a neutral and alkaline environment provokes the oxidation of alkenes to diols (alkene hydroxylation reaction or Wagner reaction).

The oxidation of acetylene with potassium permanganate in a slightly alkaline medium occurs with the formation of potassium oxalate. The reaction of acetylene with KMnO4 is described by the equation: 3C2H2 + 8KMnO4 = 3K2C2O4 + 2H2O + 8MnO2 + 2KOH

In an acidic environment, acetylene is oxidized to carbon dioxide: C2H2 + 2KMnO4 + 3H2SO4 = 2CO2 + 2MnSO4 + 4H2O + K2SO4

The oxidation of aldehydes, which are strong reducing agents, occurs when heated and is described by the formula: 3CH3CHO + 2KMnO4 = CH3COOH + 2CH3COOK + 2MnO2 + H2O

The oxidation of ethyl alcohol with potassium permanganate in the presence of concentrated sulfuric acid and when heated with a low flame begins with the discoloration of the solution. As a result of this reaction, brown flakes of manganese (IV) oxide fall out. If there is an excess of H2SO4, the solution becomes colorless and the smell of acetaldehyde is felt.

Oxidation of 3-nitrotoluene with potassium permanganate in an alkaline medium allows one to obtain o-nitrobenzoic acid.

The decomposition of potassium permanganate when heated is one of the ways to produce oxygen. To do this, pour KMnO4 crystals into a test tube with a gas outlet tube and then heat the test tube.

In this case, the released oxygen will flow through the tube into the flask and gradually fill it (O2 is heavier than air, so it does not leave the flask). If you place a smoldering splinter in a flask, it will burst into flames.

The reaction equation for the decomposition of potassium permanganate looks like this: 2 KMnO4 = K2MnO4 + MnO2 + O2 ↑

Cleaning moonshine with potassium permanganate and soda

The method of purifying moonshine using potassium permanganate, baking soda and alkali (for example, caustic soda) is very popular among moonshiners. Potassium permanganate removes fusel oils, baking soda neutralizes acetic acid, alkali - other harmful impurities.

In the absence of alkali, you can limit yourself to using only potassium permanganate and soda.

Sequencing:

• Potassium permanganate is diluted in water at the rate of 1.5 g per 1 liter of product.
• Soda is diluted in water. To clean 10 liters of moonshine, you need to prepare a solution of 100 g of soda and 100 ml of water.
• First pour the soda solution into the moonshine, stir, and then the potassium permanganate solution.
• Leave for half an hour.
• Dilute caustic soda (or other alkali) with water in equal proportions at the rate of 2 g per 1 liter of moonshine (the alkali is poured with water, and not poured into the water - this is important!).
• The moonshine is covered with a lid and left in a dark place for 12-14 hours, and then filtered through charcoal or cotton wool.

The use of potassium permanganate in gardening

Gardeners and gardeners know about the beneficial properties of potassium permanganate and therefore widely use potassium permanganate for plants.

Use in the garden is advisable when it is necessary to treat the seeds before planting: such treatment allows you to destroy pathogens overwintering on the seeds.

To prepare a solution of the required concentration, dissolve 0.5 g of potassium permanganate in 100 ml of water. The seeds are placed in the resulting liquid for 20 minutes and then dried.

Treating potatoes with potassium permanganate before planting helps protect the tubers from pathogenic fungi and wireworms. A dark pink solution is used to soak the tubers.

To treat onions before planting, use a pink solution. The bulbs are placed in it so that the liquid covers them and left for 8-12 hours.

For processing strawberries in the spring, a product with the following composition is well suited: 1 glass of ash, 1-2 liters of boiling water (the ash is poured with boiling water and allowed to cool), 2 g of potassium permanganate, 2 g of boric acid powder, 1 tbsp. spoon of iodine . The mixture is filtered, poured into a bucket and topped up with water, and used for spraying.

The solution acts both as a fertilizer and as a pest repellent.

A solution of potassium permanganate can be used to spill soil for seedlings, wash boxes, pots and cups before planting greenery or seedlings, and treat greenhouses and greenhouses to prevent plant diseases.

To cultivate soil, for seedlings, and water strawberries and bushes (gooseberries, raspberries, currants) in early spring, use a solution prepared in the proportions of 3 g of potassium permanganate per 10 liters of water. It is especially good to use this product on sandy soils.

However, you should not get carried away with potassium permanganate for cultivating the land and watering flowers - excessive manganese content in the soil can adversely affect the development of plants.

Spraying strawberries with a solution prepared in the proportions of 2 teaspoons of potassium permanganate per 10 liters of water saves strawberries from gray rot. Berries should be processed after flowering.

Is it possible to water seedlings with potassium permanganate? A solution of potassium permanganate is usually used to disinfect soil in boxes and cups adapted for seedlings, as well as in beds. Seedlings in cups should be watered with a warm pink solution once every ten days (alternating with watering with ash lye if desired).

Before planting any seeds in the ground, the soil in the box is watered with a solution, for the preparation of which 3-5 g of potassium permanganate is dissolved in 10 liters of water.

Many gardeners are interested in whether it is possible to water tomatoes with potassium permanganate. Experienced experts say that it is even necessary, since such treatment prevents many plant diseases.

Is it possible to water flowers with potassium permanganate? It is possible, but not too zealously, so as not to cause harm. The benefits of such irrigation with a solution of potassium permanganate are enormous.

First, the plant receives additional manganese and potassium. Secondly, the acidity of the soil increases, which favors the growth of some plants. Thirdly, the soil is disinfected.

The solution for flowers should be pale pink. To prepare it, just drop a few drops of a concentrated solution of potassium permanganate into a glass of water.

How to wash potassium permanganate off your hands?

To wash off the stains left by potassium permanganate from your hands, you can use a slice of lemon, alcohol, or 5-9% vinegar and hydrogen peroxide .

People who advise how to remove potassium permanganate from skin also note the effectiveness of a universal detergent, which is prepared from 100 g of soap (baby or laundry soap, grated on a fine grater), 100 ml of hot water, baking soda (2-3 tablespoons) and 2-3 drops of essential oil.

Potassium permanganate plus sugar: make a fire using improvised means

To start a fire without matches, you need to take a stick, a flat board, potassium permanganate and sugar. Use a stick to rub potassium permanganate and sugar vigorously. As a result of the chemical reaction, the mixture spontaneously ignites.

Precautionary measures

Potassium permanganate should not be dissolved and stored in metal containers, since potassium permanganate will interact with them and lose some of its medicinal properties. It is optimal to use glass containers for preparing aqueous solutions.

If potassium permanganate causes a burn, what should you do?

If the mouth, esophagus and stomach are burned with a concentrated solution of potassium permanganate, the victim’s stomach should be immediately washed, activated carbon and a weak solution of hydrogen peroxide with vinegar should be given (half a glass of peroxide and 1 glass of table vinegar per 2 liters of water).

Chemical properties

I won’t bore you with a lot of chemical terms, but I’ll just say that here manganese is in its highest oxidation state, so it is a very strong oxidizing agent. It is on this property that almost all uses of potassium permanganate are based:

• in laboratories as an oxidizing agent,
• in industry,
• in pyrotechnics,
• for etching wood (in other words, stain),
• as an antiseptic in medicine,
• in everyday life - for disinfection,
• seed dressing,
• Recently, this substance has become often used to remove tattoos.

What can replace potassium permanganate?

Analogs of potassium permanganate: Ammonia+glycerol+ethanol , Aseptolin , Anmarin , Baktoderm , Vitaon , Dermatolo-tar liniment , Dioxysol , Zelenka , Caleflon , Katapol , Katatcel , Naphthalan ointment , Ethyl alcohol , Protol , Hydrogen peroxide , Tambukan mud , For midron , Formagel , Elekasol , Ethol 96% , Zinc-salicylic paste , Chaga .

During pregnancy

During pregnancy , only external use of potassium permanganate is allowed. Taking potassium permanganate solution orally is contraindicated.

Determining pregnancy using potassium permanganate

This method of determining pregnancy belongs to the “grandmother’s” category, but many pregnant women claim that it is quite accurate.

A small amount of potassium permanganate powder is diluted in 500 liters of warm water (so that the liquid turns pale pink) and a little urine is added to the resulting solution.

If the liquid becomes lighter, there is no pregnancy; if a sediment in the form of flakes has fallen to the bottom of the jar, there is reason to suspect pregnancy.

Reviews

Potassium permanganate is a time-tested antiseptic , which, despite the abundance of other means, is widely used literally from birth. Reviews of potassium permanganate confirm its effectiveness for skin diseases, poisoning, cystitis , sore throat and a number of other diseases.

Some women also use potassium permanganate for unwanted hair. The reviews and photographs that accompany them allow us to conclude that with regular use of a weak solution of potassium permanganate for hair removal, the hairs become thinner and less noticeable over time.

However, there are also less optimistic reviews about hair removal with potassium permanganate - in them, women indicate that it is much safer to resort to professional hair removal with a special device.

Application

• For medical purposes, solutions of 0.01-5% are used for gargling, gastric lavage, douching, treating wounds and burns, and removing tattoos. Antidote for poisoning with morphine, alkaloids, phosphorus, hydrocyanic acid, quinine. To destroy pathogenic microflora during food intoxication. For cleaning eyes after contact with poisonous insects. To neutralize aniline that gets on the skin.
