Oxalic acid The simplest dicarboxylic acid

Oxalic acid is an organic compound with the IUPAC name ethanedioic acid and formula HO
. It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water. Its name comes from the fact that early investigators isolated oxalic acid from flowering plants of the genus Oxalis, commonly known as wood-sorrels. It occurs naturally in many foods, but excessive ingestion of oxalic acid or prolonged skin contact can be dangerous.

Oxalate Any derivative of oxalic acid; chemical compound containing oxalate moiety

Oxalate (IUPAC: ethanedioate) is the dianion with the formula C
, also written (COO)2−
. Either name is often used for derivatives, such as salts of oxalic acid, for example sodium oxalate Na2C2O4, or dimethyl oxalate ((CH3)2C2O4). Oxalate also forms coordination compounds where it is sometimes abbreviated as ox.

Sodium oxalate Chemical compound

Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na2C2O4. It is a white, crystalline, odorless solid, that decomposes above 290 °C.

Chromium(III) fluoride Chemical compound

Chromium(III) fluoride is the name for the inorganic compounds with the chemical formula CrF3 as well as several related hydrates. The compound CrF3 is a green crystalline solid that is insoluble in common solvents, but the coloured hydrates [Cr(H2O)6]F3 and [Cr(H2O)6]F3•3H2O are soluble in water. The trihydrate is green, and the hexahydrate is violet. The anhydrous form sublimes at 1100–1200 °C.

Americium dioxide (AmO2) is a black compound of americium. In the solid state AmO2 adopts the fluorite, CaF2 structure. It is used as a source of alpha particles.

Dimethyl oxalate Chemical compound

Dimethyl oxalate is the organic compound with the formula (CO2CH3)2. It is the dimethyl ester of oxalic acid. Dimethyl oxalate is a colorless or white solid that is soluble in water.

Strontium oxalate Chemical compound

Strontium oxalate is a compound with the chemical formula SrC2O4. Strontium oxalate can exist either in a hydrated form (SrC2O4nH2O) or as the acidic salt of strontium oxalate (SrC2O4mH2C2O4nH2O).

Magnesium oxalate Magnesium compound

Magnesium oxalate is an organic compound comprising a magnesium cation with a 2+ charge bonded to an oxalate anion. It has the chemical formula MgC2O4. Magnesium oxalate is a white solid that comes in two forms: an anhydrous form and a dihydrate form where two water molecules are complexed with the structure. Both forms are practically insoluble in water and are insoluble in organic solutions.

Chromium(II) oxalate is an inorganic compound with the chemical formula CrC2O4.

Thorium oxalate Chemical compound

Thorium oxalate is the inorganic compound with the formula Th(C2O4)2(H2O)4. It is a white insoluble solid prepared by the reaction of thorium(IV) salts with an oxalic acid. The material is a coordination polymer. Each Th(IV) center is bound to 10 oxygen centers: eight provided by the bridging oxalates and two by a pair of aquo ligands. Two additional water of hydration are observed in the lattice.

Lanthanum hydroxide Chemical compound

Lanthanum hydroxide is La(OH)
, a hydroxide of the rare-earth element lanthanum.

Sodium hydrogenoxalate Partly deprotonated oxalic acid

Sodium hydrogenoxalate is the sodium salt of hydrogenoxalate. The only difference from oxalic acid is that one of the two hydrogen atoms has been replaced with a sodium atom. Like oxalate, it is toxic for the kidney function if swallowed because of the precipitation of poorly soluble calcium oxalate stones that can obstruct the kidney tubules.

Caesium oxalate (standard IUPAC spelling) dicesium oxalate, or cesium oxalate (American spelling) is the oxalate of caesium. Caesium oxalate has the chemical formula of Cs2C2O4.

The nickel organic acid salts are organic acid salts of nickel. In many of these the ionised organic acid acts as a ligand.

Americium(III) hydroxide is a radioactive inorganic compound with the chemical formula Am(OH)3. It consists of one americium atom and three hydroxide groups. It was first discovered in 1944, closely related to the Manhattan Project. However, these results were confidential and were only released to the public in 1945. It was the first isolated sample of americium, and the first americium compound discovered.

Uranyl oxalate Chemical compound

Uranyl oxalate (UO2C2O4) is a pale yellow powdered uranyl compound. It is often encountered in industrial nuclear processes at both the front and back-end of the nuclear fuel cycle. Due to its hygroscopicity, uranyl oxalate rarely exists in the dehydrated state and is usually instead found in the trihydrate form (UO2C2O4·3H2O) at room temperature. At room temperature, the powder exhibits a monoclinic crystal structure in the P21/c space group.

Lithium oxalate Chemical compound

Lithium oxalate is an inorganic compound, a salt of lithium metal and oxalic acid with the chemical formula C
. Lithium oxalate is highly insoluble in water and converts to the oxide when heated.

Praseodymium oxalate is an inorganic compound, a salt of praseodymium metal and oxalic acid with the chemical formula C6O12Pr2. The compound forms light green crystals, insoluble in water, also forms crystalline hydrates.

Copper oxalate Chemical compound

Copper oxalate is an inorganic compound, a salt of copper metal and oxalic acid with the chemical formula CuC
. The compound is practically insoluble in water, alcohol, ether, and acetic acid but soluble in ammonium hydroxide. Copper oxalate forms a hydrate, which forms acid-blue crystals.

Praseodymium(IV) fluoride Chemical compound

Praseodymium(IV) fluoride (also praseodymium tetrafluoride) is a binary inorganic compound, a highly oxidised metal salt of praseodymium and fluoride with the chemical formula PrF4. The compound forms light yellow crystals.
