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 ...
Potassium permanganate is an oxidizing agent. [5] The British National Formulary recommends that each 100 mg be dissolved in a liter of water before use. [3] Potassium permanganate was first made in the 1600s and came into common medical use at least as early as the 1800s. [6] It is on the World Health Organization's List of Essential Medicines ...
Jmol is computer software for molecular modelling chemical structures in 3-dimensions. [2] Jmol returns a 3D representation of a molecule that may be used as a teaching tool, [ 3 ] or for research e.g., in chemistry and biochemistry .
A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 4, the conjugate base of permanganic acid.Because the manganese atom has a +7 oxidation state, the permanganate(VII) ion is a strong oxidising agent.
Similar to potassium permanganate, the two-step decomposition of rubidium permanganate leads to the formation of rubidium manganate intermediates. It breaks down into manganese dioxide, rubidium oxide and oxygen. [4] The decomposition temperature is between 200 and 300 °C. [7] Drift-away oxygen caused an 8% mass loss in the product. [7]
Permanganic acid has also been prepared through the reaction of hydrofluorosilicic acid with potassium permanganate, [4] through electrolysis, and through hydrolysis of manganese heptoxide, though the last route often results in explosions. [5] Crystalline permanganic acid has been prepared at low temperatures as the dihydrate, HMnO 4 ·2H 2 O. [3]
Similar to potassium permanganate, the two-step decomposition of caesium permanganate leads to the formation of caesium manganate intermediates. It breaks down into manganese dioxide, caesium oxide and oxygen. [5] The decomposition temperature is between 200 and 300 °C. [6] Drift-away oxygen caused an 8% mass loss in the product. [6]
Silver permanganate is an inorganic compound with the chemical formula AgMnO 4. This salt is a purple crystal adopting a monoclinic crystal system . [ 1 ] It decomposes when heated or mixed with water, and heating to high temperature may lead to explosion.
