The purplish-black color of solid potassium permanganate, and the intensely pink to purple color of its solutions, is caused by its permanganate anion, which gets its color from a strong charge-transfer absorption band caused by excitation of electrons from oxo ligand orbitals to empty orbitals of the manganese(VII) center.
Potassium permanganate is a crystalline solid that is typically dissolved in water before application to the contaminated site. [3] Unfortunately, the solubility of potassium permanganate is dependent on temperature. Because the temperature in the aquifer is usually less than the temperature in the area that the solution is mixed, the potassium ...
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 ...

Potassium permanganate (KMnO 4) oxidizes primary alcohols to carboxylic acids very efficiently. This reaction, which was first described in detail by Fournier, [10] [11] is typically carried out by adding KMnO 4 to a solution or suspension of the alcohol in an alkaline aqueous solution. For the reaction to proceed efficiently, the alcohol must ...

Potassium permanganate (KMnO 4) is a dark violet colored powder. Its reaction with glycerol (commonly known as glycerin or glycerine) (C 3 H 5 (OH) 3) is highly exothermic, resulting rapidly in a flame, along with the formation of carbon dioxide and water vapour: 14 KMnO 4 (s) + 4 C 3 H 5 (OH) 3 (l) → 7 K 2 CO 3 (s) + 7 Mn 2 O 3 (s) + 5 CO 2 ...
