Due to incomplete action of dye and oxidizer sometimes there is an allergic reaction which causes discomfort and itchiness. On heating, permanganate crystals decompose to release oxygen. 2KMnO4+ 5Na2SO3 + 3H2SO4 2MnSO4 + 5Na2SO₄ + K2SO4 + 3H2O. Potassium permanganate is a very strong oxidizing agent and can, therefore, be used as an oxidant in a wide spectrum of chemical reactions. Johann Rudolf Glauber in 1659 but was soon forgotten. When applied to small wounds, it attacks the outer cell membrane of the microorganism thereby oxidizing it and destroying its structure. Using potassium permanganate in "neutralizing" ingested nicotine, physostigmine, quinine, and strychnine is potentially dangerous. By starting the reaction, the match will consume oxygen to form carbon dioxide and water. The amount isn't critical, but don't use too much or else the solution will be too deeply colored to see the color changes. Because of its strong colour and oxidizing nature, potassium permanganate is used in chemistry labs as a reagent to calculate the amount of substance that can be oxidized in a sample. Sulfur dioxide react with potassium permanganate and water to produce sulfuric acid, manganese(II) sulfate and potassium sulfate.
