What can potassium permanganate do? Please, 3Q

Disinfection and sterilization, heating can produce oxygen, and the products are manganese dioxide and potassium manganate, potassium permanganate is a strong oxidant, which can react with highly reducing chemicals.

Remember.

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:

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

2.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. 3.

Rose red solution (about concentration) is widely used, can be used to soak fruits, vegetables, such as bayberry, cherries only need to be soaked in this concentration of solution for five minutes, and then rinsed 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.

4.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.

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.

Friends who have studied chemistry should have heard of potassium permanganate, this is a celebrity in the chemical world! So do you know what potassium permanganate is used for?

1.Potassium permanganate reacts with ethanol to form manganese dioxide, so the two are mixed to have a precipitate.

2.The reaction of potassium permanganate and hydrogen peroxide is an exothermic reaction.

3.Potassium permanganate can be used to eliminate the handwriting of blue-black ink and pure blue ink, but not the handwriting of carbon black ink, by first dropping potassium permanganate solution, and then dropping oxalic acid solution after a while, and the handwriting disappears.

In the past, my fish got white spot disease because of poor water quality, so I used potassium permanganate**theirs.

Strictly speaking, two parts per million (2ppm) of potassium permanganate is added to water and the diseased fish is soaked for 20-30 minutes. In fact, you don't have to be too strict when operating.

First of all, make about 1L of imitation water, if you add potassium permanganate, which is the size of a grain of rice like the previous millet, the water will turn dark red.

You can mix 1L of such a solution first, and then add it to your big fish pond and youqi is OK.

This amount does not need to be calculated too strictly, I have two fish tanks, one adds less of this aqueous solution (very little, colorless), and one adds more (light pink), the fish have been **successful, and now I am very happy.

Don't sprinkle potassium permanganate particles directly into it, it will hurt the fish a lot, and you will find them very excited to hide and dodge ......

Or, you can go to the place where the fish is sold, ask for the kind of solution that purifies the water, they have prepared it, and go back and add it according to the instructions. But I always think that thing has hormones, so it's better not to use it. Besides, it's suitable for a fish tank, how much do you have to use for such a big fish pond as ......

Other methods of purifying water, you can refer to the swimming pool, you can use alum, the landlord still remembers what he learned in high school chemistry class, and the gelatinous ......This method seems to be more suitable for your large fish pond.

Generally speaking, the more used is the use of potassium permanganate to disinfect, and the following will specifically talk about the general steps of using potassium permanganate for disinfection. **。

End step method.

Concentration: 1 100,000 - 1 5000, i.e. 1 to 1 5000 parts per 100,000; Due to the differences in each region, each factory, and the delivery period, there is a huge problem that the value cannot be fixed, and Chi Nasen needs to adjust it according to the method of observing visibility and color.

The method of disinfection of fish tanks, filter materials, grass, sand, stones and other equipment is - soak and scrub for 30 minutes.

The method of disinfection of fish is as follows: 10 to 15 minutes of medicated baths, during which time to ensure that there is sufficient oxygen, preferably with an air pump; If the fish is found to have only adverse reactions during the medicated bath, the water should be changed immediately or moved to other containers, and oxygen should be fully supplied; For well water fish farmers, potassium permanganate should not be used to disinfect the fish. This concentration can eliminate most germs. It can also be soaked for 2 hours at a concentration of 15 parts per million or 20 parts per million, and it can basically be completely disinfected.

When disinfection, it is recommended to use separate disinfection methods for fish, grass and equipment per mu.

Do not mix with water containing ferric iron such as well water or groundwater.

Operators operating potassium permanganate must be specially trained, strictly abide by the operating procedures, stay away from fire and heat sources, and strictly prohibit smoking, eating and drinking in the workplace. The operating environment is closed and the ventilation is strengthened. Avoid dust generation.

Avoid contact with reducing agents and active metal powders. When handling, it is necessary to load and unload lightly to prevent damage to the packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment.

Empty containers may leave harmful substances behind.

The use of potassium permanganate, a commonly used medicine in ornamental fish koi.
