What is potassium permanganate? Potassium permanganate is a common chemical compound that combines manganese oxide ore with potassium hydroxide. It was first developed as a disinfectant in 1857. Since then, it’s been widely used to treat a variety of skin conditions, including Keep reading to learn more about its medical uses and safety tips. When applied to your skin, potassium permanganate kills germs by releasing oxygen when it meets compounds in your skin. It also acts as an astringent, which is a drying agent. Some of the conditions that potassium permanganate can help treat include: • Infected eczema . If you have • Open and blistering wounds. Potassium permanganate is used as a wet dressing for wounds on your skin’s surface that are blistered or oozing pus. • Athlete’s foot and impetigo . Potassium permanganate can help to treat both bacterial and fungal skin infections such as Before applying potassium permanganate to your skin, it’s important to dilute it with water. To achieve an appropriate dilution using potassium permanganate 0.1% solution, combine 1 part potassium permanganate with 10 parts hot water. Undiluted potassium permanganate has a striking purple color, but a diluted solution should be pink. Potassium permanganate must be diluted since undiluted solution may cause burns. Even with dilution it may irritate the skin, and with repeated use may still cause burns. Potassium permanganate also comes in 400-milligram (mg) tablets. To utilize the tablets in a...

Chemical compound Potassium manganate is the K 2MnO 4. This green-colored salt is an intermediate in the industrial synthesis of KMnO 4), a common chemical. permanganate are confused, but these compounds's properties are distinct. Structure and bonding [ ] K 2MnO 4 is a salt, consisting of K + 2− 4 KMnO 4. Synthesis [ ] The industrial route entails treatment of MnO 2 with air: 2 MnO 2 + 4 KOH + O 2 → 2 K 2MnO 4 + 2 H 2O The transformation gives a green-colored melt. Alternatively, instead of using air, 2 KOH + KNO 3 + MnO 2 → K 2MnO 4 + H 2O + KNO 2 One can test an unknown substance for the presence of manganese by heating the sample in strong KOH in air. The production of a green coloration indicates the presence of In the laboratory, K 2MnO 4 can be synthesized by heating a solution of KMnO 4 in concentrated KOH solution followed by cooling to give green crystals: 4 KMnO 4 + 4 KOH → 4 K 2MnO 4 + O 2 + 2 H 2O This reaction illustrates the relatively rare role of hydroxide as a reducing agent. The concentration of K 2MnO 4 in such solutions can be checked by measuring their absorbance at 610nm. The one-electron reduction of permanganate to manganate can also be effected using 2 KMnO 4 + 2 KI → 2 K 2MnO 4 + I 2 The conversion is signaled by the color change from purple, characteristic of permanganate, to the green color of manganate. This reaction also shows that manganate(VII) can serve as an electron acceptor in addition to its usual role as an oxygen-transfer reagent. Ba...
