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
Calcium chlorate complicated by calcium hydroxide depositing on the cathode, preventing the flow of current. When concentrated solutions of calcium chlorate and potassium chloride are combined, potassium chlorate precipitates: This is the second step of the Liebig process for the manufacture of potassium chlorate. Solutions of calcium chlorate react with solutions of alkali carbonates to give a precipitate of calcium carbonate and the alkali chlorate in solution: On strong heating, calcium chlorate decomposes to give oxygen and calcium chloride: Cold, dilute solutions of calcium chlorate and sulfuric acid react to give a precipitate of calcium sulfate and chloric acid in solution: Contact
