it depends on pH
after browsing melanin bleach, it says that you require acid mixed with it
it stain as MnO2 after oxidizing here and there, but removable with oxalic acid or citric acid
Potassium permanganate can usually be obtained from chemical supply stores, pharmacies, online retailers, or agricultural suppliers. It is important to exercise caution when handling potassium permanganate, as it is a strong chemical oxidant and can cause skin irritation.
Potassium permanganate (KMnO4) is a dark purple, crystalline compound that is commonly used as an oxidizing agent in various chemical reactions. It is soluble in water and known for its powerful oxidizing properties.
No, you should not bathe a dog in potassium permanganate. It can be toxic if ingested or absorbed through the skin, and could cause irritation or other health issues for the dog. It is not safe to use for bathing pets.
To dissolve potassium permanganate (KMnO4) in water, simply add the solid crystals to water and stir gently. The crystals will dissolve as you stir, forming a purple solution. Be cautious as KMnO4 is a strong oxidizing agent and can stain and irritate skin and clothing.
no, the reaction will cause an inflammation of the burns, which will lead to certain death. don't even look at the water....
KNMnO4 solution is a purple-colored potassium permanganate solution. It is commonly used as an oxidizing agent in various chemical reactions and laboratory experiments. It is important to handle it cautiously as it is a strong oxidizer and can cause skin irritation or burns.
Potassium permanganate may be added with water and used as a disinfectant in the treatment of skin disorders. It can be used to remover sulphides and iron form well and waste water. It is used in the synthesis of ascorbic acid, saccerine and others. If mixed with concentrated hydrochloric acid it will produce chlorine gas. Mixed with concentrated sulphuric acid it becomes explosive.
It is not needed to explain it to you because a simple example will give you your answer. Bleaching is not that much harmful if done rarely. But when it is practiced often, then the amount of harm which comes to the clothes after applying bleach or stain remover is equal to the amount of harm which comes to the skin after bleaching so frequently.
The solution that is commonly used to stain skin cells is called hematoxylin and eosin (H&E). It is a popular staining method in histology that helps to differentiate cell nuclei and cytoplasmic components in tissues.
Potassium permanganate is a chemical compound with formula KMnO4 . It is violet-black in colour. It consists of Potassium, manganese and oxygen atoms. It is an oxidizing agent as here manganese is in +7 oxidation state. It is very soluble in water giving purple solutions. It can oxidize aldehydes to carboxylic acids, and secondary alcohols into ketones. It dissolves in many acids to give Manganese(II) salts. It is also reduced in strong alkaline conditions to Manganate (MnO4-2) ions, which are greenish in colour. It is a strong oxidizer, so it may cause many organic materials to catch fire on its contact. It can stain the skin, to brown colour. It has a horrible taste, and it will also stain the tongue and damage some taste buds. It also has antiseptic properties, so it is sometimes used in water purification.
"Hard scrubbing with water or scrubbing with Sodium Bisulfite solution." Good answer! It worked like a charm. I used saturated sodium bisulfite, aqueous. I've gotten the habit of first trying Nochromix in concentrated sulfuric acid for cleaning laboratory glassware. This doesn't work at all for glass bottles which have contained an aqueous solution of 1% potassium permanganate for many years. So I doubt that the other answer here, namely, to use lemon juice, would work at all since this is a much weaker acid than sulfuric. Caution: If you don't rinse out the sulfuric acid before trying sodium bisulfite, you must do this in a fume hood or a well-ventilated area since SO2 gas (or some other nasty respiratory irritant) evolves.
Removal of such a stain depends on the substance that caused it. Regardless of the substance, it is inadvisable to use strong detergents that may bleach the skin on the hands.
