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 ...
Cerium(III) oxalate (cerous oxalate) is the inorganic cerium salt of oxalic acid. It is a white crystalline solid with the chemical formula of Ce 2 (C 2 O 4 ) 3 . It could be obtained by the reaction of oxalic acid with cerium(III) chloride .
Calcium oxalate (in archaic terminology, oxalate of lime) is a calcium salt of oxalic acid with the chemical formula CaC 2 O 4 or Ca(COO) 2. It forms hydrates CaC 2 O 4 ·nH 2 O, where n varies from 1 to 3. Anhydrous and all hydrated forms are colorless or white.
It can also be prepared by treating oxalic acid with phosphorus pentachloride. [6] [7] Oxalyl chloride is produced commercially from ethylene carbonate. Photochlorination gives the perchloroethylene carbonate C 2 Cl 4 O 2 CO and hydrogen chloride HCl, which is subsequently degraded to oxalyl chloride and phosgene COCl 2: [8] C 2 H 4 O 2 CO + 4 ...
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).
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−. Ammonium oxalate sometimes comes as a monohydrate ([NH 4] 2 C 2 O 4 ·H 2 O). It is a colorless or white salt under standard conditions and is odorless and non ...
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.
Tin(II) oxalate is an inorganic compound, a salt of tin and oxalic acid with the chemical formula SnC 2 O 4. [2] The compound looks like colorless crystals, does not dissolve in water, and forms crystalline hydrates.
