Barium chlorate in some sodium contamination, which is undesirable for pyrotechnic purposes, where the strong yellow of sodium can easily overpower the green of barium. Sodium-free barium chlorate can be produced directly through electrolysis: It can also be produced by the reaction of barium carbonate with boiling ammonium chlorate solution: The reaction initially produces barium chlorate and ammonium carbonate; boiling the solution decomposes the ammonium carbonate and drives off the resulting ammonia and carbon dioxide, leaving only barium chlorate in solution. When exposed to heat, barium chlorate alone will decompose to barium chloride and oxygen: Barium chlorate is used to produce chloric
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
