Why can t potassium permanganate be washed off on the skin?

In fact, those yellow colors are not because ** is oxidized, but the manganese dioxide produced by the decomposition of potassium permanganate has strong adhesion, you just need to buy some, or go to the laboratory to take some oxalic acid, dissolve it and wash your hands, you can remove the yellow color on **, and oxalic acid is a completely non-toxic chemical, do not worry about health problems. I have personally used this method many times, so it is recommended to use it.

Potassium permanganate has strong oxidizing properties, ** is oxidized, so it can't be washed off, and it will be gone after a few days.

Because potassium permanganate has strong oxidizing properties, it is oxidized when it sticks to **, so it can be washed with water juice liquid.

The cleaning methods of potassium permanganate are: alkaline soap, natural water, hydrogen peroxide, salt water, lemon.

1. Alkaline soap

Potassium permanganate can be cleaned with alkaline soap.

2. Natural water

If the concentration of potassium permanganate is too high, it will be corrosive, and it can be rinsed repeatedly with natural water, so that potassium permanganate can generally be washed off.

3. Hydrogen peroxide

In addition, it can also be cleaned with hydrogen peroxide appropriately, which also has a certain effect.

4. Salt water

Wash with salt water. The solution dose is 500 ml of water with the addition of grams of vitamin C. Since potassium permanganate is acidic, you can use alkaline things to clean, such as soap, soap, etc.

5. Lemon

It is also possible to wash off with fresh lemon. A few drops of 3 percent hydrogen peroxide can be applied to the top to remove. After potassium permanganate gets on your hands, as long as you are not harmed, you can wash it off.

1. Potassium permanganate can be washed off with hydrogen peroxide, soap, salt water, oxalic acid, citric acid and vitamin C on clothes.

2. If you get it, you can add 5 vitamin C tablets with a dosage of grams to 500 ml of 38 warm boiled water (suitable warm water), prepare a 1% solution, dip a cotton ball in the solution and wash the affected area directly.

1. Potassium permanganate, commonly known as gray manganese oxygen, can be soaked in citric acid or 2% oxalic acid aqueous solution, and the stain can be removed through chemical reaction.

2. Potassium permanganate can also be washed off with hydrogen peroxide, soap, salt water, oxalic acid and vitamin C on clothes. Potassium permanganate is a strong oxidant, and vitamin C is a strong reducing agent, so vitamin C can easily remove the black mark of potassium permanganate.

When using potassium permanganate, it should be noted that potassium permanganate is a strong oxidizing agent. Occurs in the presence of sulfuric acid, ammonium salts, or hydrogen peroxide**. In case of glycerol and ethanol, it can cause spontaneous combustion. There is a risk of combustion** when it is in contact with or mixed with organic matter, reducing agents, flammable substances such as sulfur and phosphorus.

Solution: Using the principle of full reaction between the soapy alkali solution and potassium permanganate, the clothes dyed with potassium permanganate can be washed.

For example, to wash clothes stained with potassium permanganate, the specific steps are as follows:

1. First prepare the basin, soap, and alkaline noodles, as shown in the figure below.

2. Then pour the water into the basin, and then soak the dyed clothes in the basin for ten minutes, as shown in the picture below.

3. Next, while soaking the clothes, put a small piece of soap into the kettle, as shown in the picture below.

4. Then, put in an appropriate amount of alkali to boil, wait for the soapy alkali solution to boil, pour it into a basin, and soak the clothes for ten minutes, as shown in the figure below.

5. Next, after soaking, you can clearly see that most of the dye has been soaked, as shown in the figure below.

6. Finally, you can repeatedly scrub the stained area with your hands, as shown in the figure below.

Notes:

First put a small piece of soap into the kettle, be sure to heat and boil the soap to completely dissolve, the soap block will become a solution, otherwise there will be no washing effect.
