Barium chlorate is a white crystalline solid. It is an irritant, as are all barium compounds. If consumed, barium chlorate can cause nausea, vomiting, and diarrhea. It is used in pyrotechnics to produce a green color. A powerful oxidizing agent, the compound is used to manufacture explosives and matches.

Synthesis

Barium chlorate can be produced through a double replacement reaction of barium chloride and sodium chlorate.

• BaCl₂ + 2 NaClO₃ → Ba(ClO₃)₂ + 2 NaCl

It can also be produced through a more complicated non-electrolytic process.

1. BaCl₂ + Na₂CO₃ → BaCO₃ + 2 NaCl or BaCl₂ + 2 NaHCO₃ → BaCO₃ + 2 NaCl + H₂O + CO₂ — In this step barium carbonate is produced, which will be used later.
2. C₄H₆O₆ + NH₄OH → NH₄C₄H₅O₆ + H₂O — in this step ammonium bitartrate is produced.
3. NH₄C₄H₅O₆ + KClO₃ → KC₄H₅O₆ + NH₄ClO₃ — in this step, the ammonium bitartrate is added to potassium chlorate, which produces potassium bitartrate, but more importantly, ammonium chlorate.
4. 2 NH₄ClO₃ + BaCO₃ + Q → Ba(ClO₃)₂ + 2 NH₃ + H₂O + CO₂ — in this step, the ammonium chlorate is added to the barium carbonate and boiled, to produce barium chlorate^[1].
