The word "permanganate" is spelled pərˈmæŋɡəneɪt. The initial "per" is pronounced with a schwa sound, followed by a stress on the second syllable "man". The "g" is pronounced with a hard "g" sound, followed by the "a" pronounced as a short "a". The final syllable "nate" is pronounced with a stress on the second syllable, and the "a" sound is pronounced as a long "a". This word refers to a chemical compound commonly used as an oxidizing agent in various applications.
Permanganate is a chemical compound composed of a permanganate ion (MnO4-) combined with another element or group of elements. It is an extremely strong oxidizing agent and is commonly used for its powerful disinfectant properties. The permanganate ion consists of one manganese atom bonded to four oxygen atoms in a tetrahedral arrangement. The ion has a -1 charge and exhibits a deep purple color.
In many applications, potassium permanganate (KMnO4) is the most commonly used permanganate compound. It is a crystalline solid that dissolves easily in water, forming a deep purple solution. Potassium permanganate is highly reactive and is commonly employed as an oxidizing agent in various chemical reactions, such as the oxidation of organic compounds or the removal of impurities from water. It is also widely utilized for its disinfecting properties, as it is effective in killing bacteria, viruses, and fungi.
Sodium permanganate (NaMnO4) is another form of permanganate compound, with similar oxidizing and disinfecting properties. Although less commonly used than potassium permanganate, sodium permanganate is still employed in certain industrial applications, such as the production of dyes and pharmaceuticals.
Overall, permanganate compounds are known for their potent oxidizing and disinfecting abilities, making them useful in various chemical processes and applications.
The word "permanganate" is derived from the combination of two separate terms: "per-" and "manganese".
The prefix "per-" is derived from the Latin word "per", which means "through", "thoroughly", or "completely". In chemical terminology, the prefix "per-" is used to indicate a higher oxidation state or a larger amount of a particular element.
The second part of the word, "manganese", refers to the chemical element with the atomic number 25. The term "manganese" is derived from the Latin word "magnes", which means "magnet".
Therefore, combining these two parts, "permanganate" can be understood as a compound that contains a higher oxidation state of manganese, specifically the Mn(VII) oxidation state. Permanganate compounds are known for their vibrant purple color and powerful oxidizing properties.
