It is an odourless, purple to magenta crystalline solid. f2413, XX.1.1 Simple oxo-compounds of manganese (oxomanganates). It is a dark purple odourless solid in its physical state. Dipak B. Datta, Ivan J. Ryrie, Andre T. Jagendorf. One manganese atom is attached to the four oxygen atoms in the permanganate anion. The reaction is as follows: When permanganate reacts with concentrated hydrochloric acid it produces chlorine. In a neutral solution, permanganate is reduced by three electrons to produce manganese dioxide, where the oxidation state of manganese is +4. It dissolves in water to give deep purple solutions, evaporation of which gives prismatic purplish-black glistening crystals. This study describes the creation and characterization of encapsulated KMnO4 particles, the purpose of which is to serve as a material that can be specifically targeted and delivered to a contaminant source zone for optimal oxidative destruction of the … the manganate and permanganate ions are tetrahedral.

Potassium Permanganate structure – KMnO4 Potassium permanganate is an ionic compound consisting of a potassium cation (K+) and permanganate anion (MnO4-). Note that this compound features an ionic bond between the potassium cation and the permanganate anion. Therefore, permanganate a good oxidizing agent. KMnO4 (Potassium Permanganate) - Structure, Preparation, Properties, Uses Potassium Permanganate - KMnO4 is the chemical formula of Potassium permanganate, which is most commonly used as an oxidising agent in volumetric analysis. Potassium permanganate is the chemical compound K MnO 4.In this salt, manganese is in the +7 oxidation state. The Mn–O distances are 1.62 Å. It is an odourless, purple to magenta crystalline solid. R. D. Brown, B. H. James, M. F. O'Dwyer. KMnO4 acts as a very powerful oxidizing agent in acidic, neutral and alkaline media.
