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
The name corresponding to this formula is "potassium manganite".
bleach blue somthing
no, the reaction will cause an inflammation of the burns, which will lead to certain death. don't even look at the water....
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.
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.
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 depends on how deep the stain is.the top layer of skin on you is realy dead skin.
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.
With skin bleach.
Mix hydrogen peroxide with an equal amount of water. (Half/Half) Gently rub out the stain. If it is on the outside of the skin it will come off. Be careful to not get the peroxide near your eyes. The peroxide will bleach any cloth that it touches.
No, no it doesn't. Don't TRY to bleach your skin, it ultimately leads to cancer.
No it does not. Bleach only whitens clothes. Bleach is toxic and can kill if swallowed. Be safe. +++ That's true but no-one was suggesting drinking it. You would though, be an idiot to try to bleach your skin!
