Barium oxalate materials that are required to prepare barium oxalate are oxalic acid and barium hydroxide (or its octahydrate). It can also be prepared by using an oxalic acid solution and a barium chloride solution, with the reaction as follows: Barium oxalate Barium oxalate (BaCO), a barium salt of oxalic acid, is a white odorless powder that is sometimes used as a green pyrotechnic colorant generally in specialized pyrotechnic compositions containing magnesium. Though largely stable, barium oxalate can be reactive with strong acids. A mild skin irritant, the substance is considered toxic when ingested, causing nausea, vomiting, renal failure, and injury to
Barium iodide to form organobarium compounds. BaI can be reduced with lithium biphenyl, to give a highly active form of barium metal. Like other soluble salts of barium, barium iodide is toxic. Barium iodide Barium iodide is an inorganic compound with the formula BaI. The compound exists as an anhydrous and a hydrate (BaI(HO)), both of which are white solids. When heated, hydrated barium iodide converts to the anhydrous salt. The hydrated form is freely soluble in water, ethanol, and acetone. The structure of the anhydrous form resembles that of lead(II) chloride with each Ba center bound to nine iodide ligands and
