Addition of concentrated sulfuric acid to potassium permanganate gives Mn 2 O 7. [76] Although no reaction may be apparent, the vapor over the mixture will ignite paper impregnated with alcohol. Potassium permanganate and sulfuric acid react to produce some ozone, which has a high oxidizing power and rapidly oxidizes the alcohol, causing it to ...
A permanganate can oxidize an amine to a nitro compound, [7] [8] an alcohol to a ketone, [9] an aldehyde to a carboxylic acid, [10] [11] a terminal alkene to a carboxylic acid, [12] oxalic acid to carbon dioxide, [13] and an alkene to a diol. [14] This list is not exhaustive. In alkene oxidations one intermediate is a cyclic Mn(V) species: [15]
K 2 MnO 4 is a salt, consisting of K + cations and MnO 2− 4 anions. X-ray crystallography shows that the anion is tetrahedral, with Mn-O distances of 1.66 Å, ca. 0.03 Å longer than the Mn-O distances in KMnO 4. [2] It is isostructural with potassium sulfate. The compound is paramagnetic, owing to the presence of one unpaired electron on the ...
It is the sodium salt of oxalic acid. It contains sodium cations Na + and oxalate anions C 2 O 2− 4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. [2] Sodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO 4) solutions.
In weak acidic medium MnO − 4 can not accept 5 electrons to form Mn 2+. Instead, it accepts only 3 electrons and forms solid MnO 2 by the following reaction: MnO − 4 + 4 H + + 3 e − → MnO 2 + 2 H 2 O; E° = +1.69 V. In a strongly basic solution, with the concentration c (NaOH) >1 mol dm −3, only one electron is accepted to produce ...
Permanganic acid (or manganic(VII) acid) is the inorganic compound with the formula H MnO 4 and various hydrates. [3] This strong oxoacid has been isolated as its dihydrate. It is the conjugate acid of permanganate salts. It is the subject of few publications and its characterization as well as its uses are very limited.

Sodium permanganate behaves similarly to potassium permanganate. It dissolves readily in water to give deep purple solutions, evaporation of which gives prismatic purple-black glistening crystals of the monohydrate NaMnO 4 ·H 2 O. The potassium salt does not form a hydrate.
