Potassium permanganate is an inorganic compound with the chemical formula KMnO 4. It is a purplish-black crystalline salt, which dissolves in water as K + and MnO − 4 ions to give an intensely pink to purple solution.
The exothermic (heat producing) reaction between potassium permanganate (KMnO 4), a strong oxidizing agent, and glycerol (C 3 H 5 (OH) 3), a readily oxidised organic substance, is an example of an experiment sometimes referred to as a "chemical volcano". [7] [8]
For instance, potassium permanganate decomposes at 230 °C to potassium manganate and manganese dioxide, releasing oxygen gas: 2 KMnO 4 → K 2 MnO 4 + MnO 2 + O 2 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 ...
Soluble fiber from foods such as [name of soluble fiber source, and, if desired, name of food product], as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease. A serving of [name of food product] supplies __ grams of the [necessary daily dietary intake for the benefit] soluble fiber from [name of soluble ...
The effectiveness of water-soluble antioxidants is limited in preventing direct oxidation within fats, but is valuable in intercepting free radicals that travel through the aqueous parts of foods. A combination of water-soluble and fat-soluble antioxidants is ideal, usually in the ratio of fat to water.
Sophomore wide receiver Eric Singleton Jr., one of the top skill-position targets in the transfer portal, is headed to Auburn to catch passes from Jackson Arnold.
With a dominant defense leading the way, the Green Bay Packers clinched a playoff berth by producing their most lopsided win in a decade. Josh Jacobs gained 107 yards from scrimmage and scored a ...
Resistant starch is considered both a dietary fiber and a functional fiber, depending on whether it is naturally in foods or added. [ 51 ] [ 52 ] [ 53 ] Although the U.S. Institute of Medicine has defined total fiber as equal to functional fiber plus dietary fiber, [ 54 ] U.S. food labeling does not distinguish between them.
