Potassium Permanganate is a chemical compound that can release oxygen and kill bacteria. Therefore, this content is often found in drugs to clean wounds on the skin. This compound is a substance that is easily soluble in water so that its use is easier . Have you never heard of this before?
Let’s find out more inorganic compound examples and the chemical formula potassium permanganate, how much is the price and where it can be purchased, what are the dangers also benefits of the uses of potassium permanganate in daily life? Immediately see the review below.
- What is Potassium Permanganate?
Potassium permanganate has another name, chameleon mineral, CI 77755, condy crystal and cairox. It is a purple crystal that becomes bronze and stable. If contact with flammable compounds will cause a fire and be kept away from reducing compounds, strong acids, organic materials, peroxides, alcohols and active metal chemical compounds like we found in fireworks elements. Potassium permanganate is a strong oxidizing agent. The physical properties of potassium permanganate are purple crystals such as bronze crystals and melting points of 1050C (decomposed).
Potassium Permanganate is a class of antioxidants that can release oxygen (oxidation process) so that it can kill germs (baktericidal). Potassium permanganate is a purple crystal, easily soluble in water and produce concentrated purple solutions.
In a dilute solution is a antioxidant. Release of oxygen occurs when these substances come into contact with organic substances. Inactivation causes changes in the color of the solution from purple to blue.
Potassium Permanganate has the chemical formula KMnO4. This compound is also a salt containing ions. Not only that, potassium permanganate is an inorganic chemical compound that is often used to clean wounds but this compound can also work as deodorant, irritant, and astringent.
The physical properties of these compounds include physical, odor, weight, taste, and color. The physical properties of this compound are solid, powdery, and almost like cake crumbs. Then this compound has no odor even though when inhaled it can be dangerous. The molecular weight of this compound is 158.03 grams / mol. This compound has a thick purple color.
- Uses of Potassium Permanganate in Daily Life, such as :
1. It is used in Redox Titration
Redox titration is the type of titration with the most types, including:
- Iodimetry, iodometry, iodatometry
- Bromometry, bromatometry
Permanganometry is a titration that is carried out based on the reaction by potassium permanganate (KMnO4). This reaction is focused on oxidation reactions and the reduction that occurs between KMnO4 and certain raw materials. Titration with KMnO4 has been known for more than a hundred years which is studied under branches of analytical chemistry. Most titrations are carried out directly on oxidizable devices such as Fe +, acid or soluble oxalate salts and so on. Some non-oxidized metal ions can be indirectly titrated by permanganometry such as: (1) Ca, Ba, Sr, Pb, Zn, and Hg (I) ions which can be precipitated as oxalate.
After the sediment is filtered and washed, it is dissolved in excess H2SO4 so that quantitative oxalic acid is formed. This oxalic acid is finally titrated and the titration results can be calculated by the number of metal ions in question. (2) Ba ions and Pb can also be precipitated as chromatous salt. After being filtered, washed, and dissolved with acid, additional FeSO4 standard solution was added. Some Fe2 + is oxidized by the chromate and the rest can be determined by its amount by KMnO4.
One thing to be notice in titration by using potassium manganate is: potassium manganate (VII) cannot be used in titrations containing chloride or bromide ions in which the two ions can be oxidized. Unknown amounts of potassium manganate (VII) are used in side reactions, and certainly the titration results are not accurate. This is why you should not acidify the solution with hydrochloric acid like in Acid Solution Examples.
2. This substance works as an irritant, deodorant and astringent.
3. Used to compress wounds and all kinds of skin infections.
4. As an antidote to intoxication of easily oxidized substances such as alkaloids, chloralhydrate and barbiturates.
5. Used in irrigation of infected bladder
6. As postpartum perineal washers
7. As antiseptic, and astringent.
In dermatitis 1 / 10,000 dilution is used, while the infection uses 1/5000 dilutions. In dermatitis, the skin is sensitive, because it is used which is more watery. If the concentration is stronger than 1: 5000 it can irritate the skin. This liquid is cheap and often used, the deficiency is red, so it color the skin and clothing.
- What is the Price of Potassium Permanganate ? Where to buy?
As mentioned before, these inorganic chemicals can be used for human needs such as cleaning wounds that is also the use of hydrogen peroxide in many hospitals and health clinics. So, it’s good to keep some at home. These chemical compounds can be purchased online or in chemical stores, but are not sold at pharmacies.
Currently, the price of potassium permanganate is IDR 7 thousand per gram. Although it can be purchased at a chemical store, its use (for cleaning wounds) must be based on a doctor’s consultation to avoid infection or other undesirable things.
- Dangers of potassium permanganate
In this case, this inorganic chemical compound has a hazard label so that anyone who wants to use it must really know what it is doing. Then, the potassium permanganate is also easy to react when it is brought close to metal, ammonia, sulfur, and acid. This chemical compound is also flammable.
The second thing from the MSDS is the properties found in this chemical compound. The first characteristic is the nature of danger that leads to health.
- The first danger of potassium permanganate is contact with the eye which can cause eye damage and lead to blindness.
- If it is burned and the smoke is inhaled, this compound can cause irritation to the respiratory tract, kidneys, liver, intestines, even the central nervous system.
- If too much is inhaled, this compound can damage the lungs and lead to death.
- Caution of Potassium Permanganate :
Potassium permanganate can cause serious health effects such as:
- Inhalation: Causes irritation to the respiratory tract. Symptoms can include coughing, shortness of breath. High concentration can cause pulmonary edema.
- Ingestion: Consuming solid or high concentrations causes suffering from the weight of the gastro-intestinal system with possible burns and edema, slow pulses; shock with the fall of blood pressure. Swallowing concentrations of up to 1% cause burning of nausea, throat, vomiting, and abdominal pain; 2-3% cause anemia and swelling of the throat with possible weakness; 4-5% can cause kidney damage.
- Skin contact: dry crystals and concentrated solutions are caustic causing redness, pain, burns, brown spots in the contact area and possible hardening of the outer skin layer
- Eye contact: Eye contact with crystals (dust) and concentrated solutions cause severe irritation, redness, blurred vision and can cause severe damage, possibly permanent. When exposed to eyes or skin, rinse immediately with cold water and seek medical attention.
- Chronic exposure: prolonged skin contact can cause irritation, defatting, and dermatitis, chronic manganese poisoning can result from excessive dust inhalation exposure to manganese and involve a decrease in the central nervous system.
That’s all the uses of potassium permanganate in daily life. Hope this article is useful.
