Barium Chlorate is a white crystaline solid. It is an irritant, and if consumed can cause nausea, vomiting, and diarrhoea. It is used in pyrotechnics to produce a green colour.

[edit] Synthesis

Barium chlorate can be produced through a double displacement 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. C2O6H6 + NH4OH → C2O6H5NH4 + H2O — in this step tartaric acid is produced.
  3. C2O6H5NH4 + KClO3 → C2O6H5K + NH4ClO3 — in this step, the tartaric acid is added to potasium chlorate, which produces potasium 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].
