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.
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.
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−. Ammonium oxalate sometimes comes as a monohydrate ([NH 4] 2 C 2 O 4 ·H 2 O). It is a colorless or ...
In addition to the neutral rubidium oxalate Rb 2 C 2 O 4, there is also an acidic salt, rubidium hydrogen oxalate with the formula RbHC 2 O 4, which is isomorphic to potassium hydrogen oxalate KHC 2 O 4 [10] and forms monoclinic crystals, [11] and an acidic dioxalate with the formula RbHC 2 O 4 ·H 2 C 2 O 4, which exists as a dihydrate, has a ...
The compound is a salt consisting of ferrioxalate anions, [Fe(C 2 O 4) 3] 3−, and potassium cations K +. The anion is a transition metal oxalate complex consisting of an iron atom in the +3 oxidation state and three bidentate oxalate C 2 O 2− 4 ligands. Potassium is a counterion, balancing the −3 charge of the complex.
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.

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.
