This behaviour is also used as a qualitative test for the presence of double or triple bonds in a molecule, since the reaction decolorizes the initially purple permanganate solution and generates a brown precipitate (MnO2). Potassium permanganate is added to "plastic sphere dispensers" to create backfires, burnouts, and controlled burns. It can dissolve in water, and it is a strong oxidant. In this context, it is sometimes called Baeyer's reagent. The compound is odourless i.e. Sodium permanganate (MnNaO 4) and potassium permanganate (MnKO 4) are the sodium and potassium salt of permanganic acid respectively. It is sometimes referred to as Baeyer's reagent after the German organic chemist Adolf von Baeyer . Weeks, Mary Elvira with Henry M. Leicester, ed.. "Handbook of Preparative Inorganic Chemistry" Brauer, E., Ed. This material contains Potassium permanganate (listed as Manganese compounds, n.o.s. Harmful if swallowed. Although effective, the solution was not very stable. It can also be used to control iron bacteria growth in wells. Potassium permanganate, the common laboratory chemical, can be easily purchased from a manufacturer, wholesale dealer, or chemical supplier in India.This has been a long-followed trend but has major drawbacks with regards to quality, pricing, and delivery time. By removing ethylene by oxidation, the permanganate delays the ripening, increasing the fruit's shelf life up to 4 weeks without the need for refrigeration. Potassium Permanganate Melting Point: 464°F (240°C) Potassium Permanganate Molar Mass: 158.034 g/mol; ... Potassium permanganate is a point-of-entry treatment method that oxidizes dissolved iron, manganese, and hydrogen sulfide into solid particles that are filtered out of the water. Polymer spheres resembling ping-pong balls containing small amounts of permanganate are injected with ethylene glycol and projected towards the area where ignition is desired, where they spontaneously ignite seconds later. [5], Potassium permanganate is used extensively in the water treatment industry. Potassium Permanganate: Synonyms: Permanganate of Potash, Potassium manganite (IV) Formula: KMnO4: Purity: ACS: CAS Number: 7722-64-7: Molecular Weight: 158.03: Color & Form: Dark violet crystalline: Melting Point: 240° C (dec.) Specific Gravity: 2.71 gm/ml: Solubility: Soluble: Options. The physical state of potassium permanganate is an odorless solid, and they look like dark purple or bronze colored crystals. [29], In agricultural chemistry, it is used for estimation of available nitrogen in soil. ... No melting but decomposition occurs.

[34] In the solid (as in solution), each MnO4− centres are tetrahedral. The Mn-containing products from redox reactions depend on the pH. [12], A major application of KMnO4 is as a reagent for the synthesis of organic compounds. Potassium Permanganate is a dark purple crystalline compound, used as an oxidizing agent and disinfectant and in deodorizers and dyes. Potassium permanganate, also known as permanganate of potash or Condy's crystals, is a chemical compound consisting of two ions: a potassium ion and a permanganate ion. Potassium permanganate is a strong oxidizing agent. 240° dec. Density. In a hurry? Commodity: Potassium Permanganate Molecular formula:KMnO4 Molecule Weight:158.03 CAS:7722-64-7 EINECS:231-760-3 UN 1490 Hazard Class: 5.1 Physical State: Needle-like lustrous and dark purple crystal. Glass Bottle; 1L. Sodium permanganate is the inorganic compound with the formula Na MnO 4.It is closely related to the more commonly encountered potassium permanganate, but it is generally less desirable, because it is more expensive to produce.It is mainly available as the monohydrate.This salt absorbs water from the atmosphere and has a low melting point. Shop a large selection of products and learn more about Potassium Permanganate Solution, 0.1N (N/10) (Certified), Fisher Chemical. It has a density of 2.7g/ml and its molar mass is 158.034g/mol. ), >98%, (CAS# 7722-64-7) which is subject to the reporting requirements of Section 313 of SARA Title III and 40 CFR Part 373. 1946-47]. This solution will oxidize most organic compounds and, if the solution is strongly concentrated, explosion may accompany the oxidation. You can check out as a guest! [6] This process gives potassium manganate: (With sodium hydroxide, the end product is not sodium manganate but an Mn(V) compound, which is one reason the potassium permanganate is more commonly used than sodium permanganate. hematology (1) histology (1) titration (2) Available for Sale. [33] The chlorine oxidation reaction is, And the acid-induced disproportionation reaction may be written as. The Mn–O distances are 1.62 Å.[35].
