Oxalic acid is an organic acid with the systematic name ethanedioic acid and chemical formula HO−C(=O)−C(=O)−OH, also written as (COOH) 2 or (CO 2 H) 2 or H 2 C 2 O 4. It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water.
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Hydrogenoxalate or hydrogen oxalate (IUPAC name: 2-Hydroxy-2-oxoacetate) is an anion with chemical formula HC 2 O − 4 or HO−C(=O)−CO − 2, derived from oxalic acid by the loss of a single proton; or, alternatively, from the oxalate anion C 2 O 2− 4 by addition of a proton. The name is also used for any salt containing this anion.
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 ...
Potassium hydrogenoxalate is a salt with formula KHC 2 O 4 or K + ·HO 2 C-CO 2 −.It is one of the most common salts of the hydrogenoxalate anion, and can be obtained by reacting potassium hydroxide with oxalic acid in 1:1 mole ratio.

Sodium hydrogenoxalate or sodium hydrogen oxalate is a chemical compound with the chemical formula NaHC 2 O 4.It is an ionic compound.It is a sodium salt of oxalic acid H 2 C 2 O 4.It is an acidic salt, because it consists of sodium cations Na + and hydrogen oxalate anions HC 2 O − 4 or HO−C(=O)−CO − 2, in which only one acidic hydrogen atom in oxalic acid is replaced by sodium atom.
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 a conjugate base of oxalic acid.
