Permanganate is a manganese oxoanion and a monovalent inorganic anion. It is a conjugate base of a permanganic acid. Generally purplish colored. Soluble in water. Noncombustible, but accelerate the burning of combustible material. If the combustible material is finely divided, the mixture may be explosive.

A German-Dutch chemist Johann Rudolf Glauber was the first to discover the production of KMnO 4 in the year 1659. This compound is water-soluble and consists of two ions: Permanganate ion and potassium ion. the permanganate standard also included smaller peaks that co-elute with manganate and carbonate standards suggesting permanganate may not be stable on the column. Analysis of a permanganate standard by direct infusion –ESI HRAM MS provided a positive response, but a negative response to -ESI IC-HRAM MS. The results support Permanganate aqueous solutions, MnO4−(aq.), were studied using liquid-micro-jet-based soft X-ray non-resonant and resonant photoelectron spectroscopy to determine valence and core-level binding energies. To identify possible differences in the energetics between the aqueous bulk and the solution–gas interfac 2014-07-18 · Permanganate is a chemical compound that contains the manganate VII ion (MnO 4-).

The atomic orbital basis set for the central ion has been varied systematically, and the effect of symmetric changes of bond distances has also been examined. The reaction of permanganate with concentrated hydrochloric acid gives chlorine. The Mn-containing products from redox reactions depend on the pH. Acidic solutions of permanganate are reduced to the faintly pink manganese(II) ion (Mn 2+) and water.

a salt of permanganic acid (HMnO4). Permanganate crystals are nearly black, with a greenish violet hue, while permanganate solutions are usually tinted the red-violet color of the ion. Permanganates of sodium and bivalent metals dissolve freely in water, but KMnO4 is only sparingly soluble. Permanganates are extremely unstable upon heating.

The latter is oxidized extremely rapidly. The mechanism is discussed in terms of hydride ion or hydrogen atom transfer from the anions to permanganate. Large At the endpoint there is no Fe2+(aq) left in the flask to reduce the colored permanganate ion, so when a small amount of permanganate ion is added after the Asked by Topperlearning User | 4th Jun, 2014, 01:23: PM. Expert Answer: · The manganate ion (MnO42-) is green colored and paramagnetic while The permanganate ion is believed to add to the double bond to give a cyclic intermediate a manganate ester.
