Potassium chlorate . Barium Chlorate or also known as Chloric Acid Barium Salt and its name in English is (BARIUM CHLORATE) is a white crystalline solid in which, among its main properties, it loses hydration water at 120 ºC, begins to lose oxygen at 250 ºC, it is soluble in water, in hydrochloric acid and moderately in ethylenediamine, practically insoluble in ethyl acetate and pyridine .

How to Obtain Barium Chlorate
Barium chlorate can be produced through a double substitution reaction of barium chloride and sodium chlorate.
- BaCl2 + 2 NaClO3 → Ba (ClO3) 2 + 2 NaCl
It can also be produced through a non-electrolytic process.
- BaCl2 + Na2CO3 → BaCO3 + 2 NaCl or BaCl2 + 2 NaHCO3 → BaCO3 + 2 NaCl + H2O + CO2 – Barium carbonateis produced in this step and will be used later.
- C4H6O6 + NH4OH → NH4C4H5O6 + H2O – in this step ammonium bitartrate is produced.
- NH4C4H5O6 + KClO3 → KC4H5O6 + NH4ClO3 – in this step, ammonium bitartrate is added potassium chlorate, which produces potassiumbitartrate , but more importantly, ammonium chlorate.
- 2 NH4ClO3 + BaCO3 + Q → Ba (ClO3) 2 + 2 NH3 + H2O + CO2 – in this step, ammonium chlorate is added to that of barium carbonate and cooked, to produce barium chlorate.
Furthermore, another way of preparing it is from potassium chlorate and ammonium sulfate, which is subsequently reacted with barium hydroxide or by electrolysis of Barium Chloride .
Main Physical and Chemical Hazards
Physical Hazards
Dust explosion possible if mixed with air in a powdery or granular form.
Chemical Hazards
Intense heating can cause violent combustion or explosion. In contact with organic compounds, reducing agents, ammonia-containing agents, metal powders and sulfuric acid, unstable compounds are formed against shock. The substance decomposes violently on gentle heating, on intensive heating and on burning, producing oxygen and toxic fumes, causing fire or explosion hazard. The substance is a strong oxidant and reacts with combustible and reducing materials.
Inhalation Risk
Evaporation at 20 ° C is negligible; however it can be reached quickly particle concentration in the air .
Main Effects of Short-Term and Long-Term Exposure
Effects of Short-Term Exposure
The substance irritates the eyes, the skin and the respiratory tract. The substance can have effects on various tissues and organs, eg formation of methemoglobin. The exposition can cause death. Effects may not appear immediately. Medical surveillance is recommended.
Effects of Long-Term Exposure Duration
The substance can have effects on various tissues and organs, leading to serious health disorders.
Uses of Barium Chlorate
The main use of barium chlorate is that it is used in pyrotechnics to produce a very important green color for the manufacture of fireworks, since with chlorate various the green color is produced, which is one of the most used in fireworks, apart It is one of the most used because it is one of the basic colors, therefore having green and some others, you can make various colors at your personal choice, in addition to this use it has application as a dye in dyes, a whitening ingredient in paper.
