As potassium permanganate is titrated, the solution becomes a light shade of purple, which darkens as excess of the titrant is added to the solution. In a related way, it is used as a reagent to determine the Kappa number of wood pulp. For the standardization of KMnO 4 solutions, reduction by oxalic acid is often used. [47]
Oxalic acid is used by some beekeepers as a miticide against the parasitic varroa mite. [52] Dilute solutions (0.05–0.15 M) of oxalic acid can be used to remove iron from clays such as kaolinite to produce light-colored ceramics. [53] Oxalic acid can be used to clean minerals like many other acids. Two such examples are quartz crystals and ...
It is the sodium salt of oxalic acid. It contains sodium cations Na + and oxalate anions C 2 O 2− 4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. [2] Sodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO 4) solutions.
A permanganate can oxidize an amine to a nitro compound, [7] [8] a secondary alcohol to a ketone, [9] a primary alcohol or aldehyde to a carboxylic acid, [10] [11] a terminal alkene to a carboxylic acid, [12] oxalic acid to carbon dioxide, [13] and an alkene to a diol. [14] This list is not exhaustive. In alkene oxidations one intermediate is a ...
Potassium manganate is the inorganic compound with the formula K 2 MnO 4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO 4), a common chemical. [1] Occasionally, potassium manganate and potassium permanganate are confused, but each compound's properties are distinct.
Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4.This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4).
Ammonium oxalate is a chemical compound with the chemical formula [N H 4] 2 C 2 O 4. Its formula is often written as (NH 4) 2 C 2 O 4 or (COONH 4) 2. It is an ammonium salt of oxalic acid. It consists of ammonium cations ([NH 4] +) and oxalate anions (C 2 O 2− 4). The structure of ammonium oxalate is ([NH 4] +) 2 [C 2 O 4] 2−.
it is an ingredient in Photo-Flo, a solution used in photographic processing to prevent minerals from water being deposited on the film after drying. Apart from laboratory use, Triton X-100 can be found in several types of cleaning compounds, [ 7 ] ranging from heavy-duty industrial products to gentle detergents.
