What are the applications of potassium permanganate in life?

Potassium permanganate, also known as gray manganese oxygen, commonly known as powder, is a black-purple fine crystal with a metallic luster. It is commonly used in laboratories as an oxidant and to produce oxygen. Its solutions of different concentrations have a variety of disinfection and sterilization effects, which are described as follows:

Dark purple solution (about concentration), with strong oxidation, strong sterilization ability. It can be used to disinfect baths and spittoons.

Purple-red solution (about concentration), which has the purpose of anti-itching, anti-inflammatory and anti-spread of infection, can be used to soak and wash tinea pedis

Rose red solution (about concentration) is widely used, can be used to soak fruits, vegetables, such as bayberry, cherries, only need to soak in this concentration of solution for five minutes, and then rinse with cool boiled water to achieve the purpose of sterilization

In medical treatment, this concentration solution can be used to soak mucosal parts, such as hemorrhoids. It has the effect of preventing infection, relieving itching, and relieving pain

Light cherry red solution is an extremely dilute solution, which can be used to gargle the mouth, prevent oral inflammation and tooth decay, and has deodorant and anti-inflammatory effects. It can also be used as an antidote, after drinking this concentration of solution, press the throat with your fingers to make it vomit, spit out the unabsorbed drugs or poisons, and make the residual drugs or poisons in the stomach be oxidized by potassium permanganate and become ineffective.

Potassium permanganate has strong oxidation, so it can be used to sterilize, and if you have athlete's foot, you can put half a mung bean to wash your feet! Can't put too much....Will burn**!

It is oxidized and decomposed in ethanol and hydrogen peroxide.

1. Food application: In addition to being used to disinfect food, it is known that potassium permanganate purification form can be used as an oxidation solution to reduce mold and better preserve raw fruits and vegetables.

2. Chemical production: widely used as an oxidant, such as an oxidant for saccharin, vitamin C, isoniazid and benzoic acid.

3. Medicine: used as preservative, disinfectant, deodorant and antidote in medicine.

4. Water purification and wastewater treatment: used as a water treatment agent to oxidize hydrogen sulfide, phenol, iron, manganese and organic, inorganic and other pollutants to control odor and decolorization. It is also used as bleach, adsorbent, colorant and disinfectant.

The use of potassium permanganate: used as a disinfectant and bleach agent in industry, in the laboratory, potassium permanganate is used for the identification of substances because of its strong oxidation and bright color of the solution, and the acidic potassium permanganate solution is an important reagent for redox titration. In medicine, potassium permanganate can be used for disinfection, gastric lavage.

It can be used as an oxidant, soluble in water, can be used for disinfection, and can be heated to produce oxygen, etc.

Characteristics of potassium permanganate: potassium permanganate, also known as gray manganese oxygen, PP powder, is a common strong oxidant, at room temperature is a purple-black flake crystal, easy to see light decomposition, so it needs to be stored in a cool place away from light, and it is strictly forbidden to put it with flammable materials and metal powder. Potassium permanganate is prepared from manganese dioxide.

Potassium permanganate KMNO4 Manganese +7 valence Potassium manganate K2MNO4 Manganese +6 valence The main difference between early and high school stages is the color: potassium permanganate is purple-red Potassium manganate is black, and the second is that the oxidation of potassium permanganate is much stronger than that of potassium manganate.

1. In the production of chemicals, it is widely used as an oxidant, such as an oxidant for saccharin, vitamin C, isoniazid and benzoic acid.

2. It is used as a preservative, disinfectant, deodorant and antidote in medicine.

3. In water purification and wastewater treatment, it is used as a water treatment agent to oxidize hydrogen sulfide, iron, manganese and organic, inorganic and other pollutants to control odor and decolorization. It is also used as bleach, adsorbent, colorant and disinfectant.

4. In mining metallurgy, it is used to separate molybdenum from copper, remove impurities from zinc and cadmium, and oxidants for compound flotation; It is also used as a bleaching agent for special fabrics, waxes, greases and resins, an adsorbent for gas masks, and a colorant for wood and copper.
