Barium chlorate is a white crystalline 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.
- 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.
- C4H6O6 + NH4OH → NH4C4H5O6 + H2O — in this step ammonium bitartrate is produced.
- NH4C4H5O6 + KClO3 → KC4H5O6 + NH4ClO3 — in this step, the ammonium bitartrate is added to potassium chlorate, which produces potassium bitartrate, but more importantly, ammonium chlorate.
- 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].
