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).
An oxalate nitrate is a chemical compound or salt that contains oxalate and nitrate anions (NO 3-and C 2 O 4 2-). These are mixed anion compounds. Some have third anions. Oxalate acts as a ligand, which normally complexes two metal atoms.
Oxalate sulfates are mixed anion compounds containing oxalate and sulfate. They are mostly transparent, and any colour comes from the cations. They are mostly transparent, and any colour comes from the cations.

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. The mineral form of sodium oxalate is natroxalate.
The carbonate oxalates are mixed anion compounds that contain both carbonate (CO 3) and oxalate (C 2 O 4) anions. Most compounds incorporate large trivalent metal ions, such as the rare earth elements. Some carbonate oxalate compounds of variable composition are formed by heating oxalates. [1]
Copper(II) oxalate are inorganic compounds with the chemical formula CuC 2 O 4 (H 2 O) x. The value of x can be 0, 0.44, and 1. The value of x can be 0, 0.44, and 1. Two of these species are found as secondary minerals (degradation of minerals), whewellite (monohydrate) and moolooite (0.44 hydrate). [ 3 ]
The oxalate phosphites are chemical compounds containing oxalate and phosphite anions. They are also called oxalatophosphites or phosphite oxalates. Oxalate phosphates can form metal organic framework compounds. Related compounds include the nitrite oxalates, arsenite oxalates, [1] [2] phosphate oxalates and oxalatophosphonates.
