Barium oxalate is a chemical compound with the chemical formula Ba C 2 O 4.It is a barium salt of oxalic acid.It consists of barium cations Ba 2+ and oxalate anions C 2 O 2− 4.It is a white odorless powder that is sometimes used as a green pyrotechnic colorant generally in specialized pyrotechnic compositions containing magnesium metal powder.
The tables below provides information on the variation of solubility of different substances ... Barium oxalate dihydrate: BaC 2 O 4 ·2H 2 O: 0.003: Barium oxide ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Oxalate also forms coordination compounds where it is sometimes abbreviated as ox. It is commonly encountered as a bidentate ligand. When the oxalate chelates to a single metal center, it always adopts the planar conformation. As a bidentate ligand, it forms a 5-membered MC 2 O 2 ring. An illustrative complex is potassium ferrioxalate, K 3 [Fe ...
The basicity of calcium oxalate is weaker than that of sodium oxalate, due to its lower solubility in water. Solid calcium oxalate hydrate has been characterized by X-ray crystallography. It is a coordination polymer featuring planar oxalate anions linked to calcium, which also has water ligands. [1]
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
The noble gases do not react with water, but their solubility in water increases when going down the group. Argon atoms in water appear to have a first hydration shell composed of 16±2 water molecules at a distance of 280–540 pm, and a weaker second hydration shell is found out to 800 pm. Similar hydration spheres have been found for krypton ...
