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
Calcium chlorate Calcium chlorate Calcium chlorate is the calcium salt of chloric acid, with the chemical formula Ca(ClO). Like other chlorates, it is a strong oxidizer. Calcium chlorate is produced by passing chlorine gas through a hot suspension of calcium hydroxide in water, producing calcium hypochlorite, which disproportionates when heated with excess chlorine to give calcium chlorate and calcium chloride: This is also the first step of the Liebig process for the manufacture of potassium chlorate. In theory, electrolysis of hot calcium chloride solution will give chlorate, analogous to the process used for the manufacture of sodium chlorate. In practice, electrolysis is
