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 used as a medication for a number of skin conditions. [2] This includes fungal infections of the foot, impetigo, pemphigus, superficial wounds, dermatitis, and tropical ulcers. [3] [2] For tropical ulcers it is used together with procaine benzylpenicillin. [2] [3] It can be applied as a soaked dressing or a bath. [2]
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 .
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 ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Potassium resides mainly inside the cells of the body, so its concentration in the blood can range anywhere from 3.5 mEq/L to 5 mEq/L. [14] The kidneys are responsible for excreting the majority of potassium from the body. [14] This means their function is crucial for maintaining a proper balance of potassium in the blood stream.
Several grams are produced per day in the human body within the mitochondria. [5] O 2 + e − → O − 2. Competing with its formation, superoxide is destroyed by the action of superoxide dismutases, enzymes that catalyze its disproportionation: 2 O − 2 + 2H + → O 2 + H 2 O 2. hydrogen peroxide (H 2 O 2) is also produced as a side product ...
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 ...
