Barium chlorate hazardous waste. The Environmental Protection Agency (EPA) lists barium chlorate as hazardous. 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
Barium acetate Barium acetate Barium acetate (Ba(CHO)) is the salt of barium(II) and acetic acid. Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: The reaction is performed in solution and the barium acetate crystallizes out. Alternatively, barium sulfide can be used: Again, the solvent is evaporated off and the barium acetate crystallized. Barium acetate is a white powder, which is highly soluble: at 0 °C, 55.8 g of barium acetate can be dissolved in 100 g of water. It decomposes upon heating into barium carbonate. When heated in air, barium acetate decomposes to the carbonate. It
