Barium chlorate Barium chlorate Barium chlorate, Ba(ClO), is a white crystalline solid, the barium salt of chloric acid. It is an irritant and toxic, as are all soluble barium compounds. It is sometimes used in pyrotechnics to produce a green color. It also finds use in the production of chloric acid. Barium chlorate can be produced through a double replacement reaction between solutions of barium chloride and sodium chlorate: On concentrating and chilling the resulting mixture, barium chlorate precipitates. This is perhaps the most common preparation, exploiting the lower solubility of barium chlorate compared to sodium chlorate. The above method does result
Sodium chlorate herbicides in aqueous solution is possible to some extent, so long as they are not susceptible to oxidation. The sale of sodium chlorate as a weedkiller was banned in the European Union in 2009, with existing stocks to be used within the following year. Chemical oxygen generators, such as those in commercial aircraft, provide emergency oxygen to passengers to protect them from drops in cabin pressure. Oxygen is generated by high-temperature decomposition of sodium chlorate: Heat required for this reaction is generated by oxidation of a small amount of iron powder mixed with the sodium chlorate, and the reaction consumes
