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
Sodium chlorate The Chloralkali process is an industrial process for the electrolytic production of sodium hydroxide and chlorine. It can also be synthesized by passing chlorine gas through a solution of sodium hydroxide. It is then purified by crystallization. The main commercial use for sodium chlorate is for making chlorine dioxide (ClO). The largest application of ClO, which accounts for about 95% of the use of chlorate, is in bleaching of pulp. All perchlorate compounds are produced industrially by the oxidation of solutions of sodium chlorate by electrolysis. Sodium chlorate is used as a non-selective herbicide. It is considered phytotoxic to all
