Sodium chlorate is a white crystalline solid. | [Chemical Properties]
Sodium chlorate, NaCI03, is colorless,odorless crystals with a cooling, saline taste, is soluble in water and alcohol,but must not be triturated with any combustible substance. Derived by heating and electrolyzing a concentrated acid solution of sodium chloride so that the chlorate is crystallized out. Used as an oxidizing agent and bleach (especially to make chlorine dioxide)for paper pulps, ore processing, herbicide and defoliant, substitute for potassium chlorate (sodium chlorate is more soluble in water),matches,explosives, flares,and pyrotechnics, in the recovery of bromine from natural brines,leather tanning and finishing, textile mordant,and to make perchlorates.
| [Uses]
A sulfation biosynthesis inhibitor. | [Uses]
It is oxidimetric reagent. | [Definition]
ChEBI: An inorganic sodium salt that has chlorate as the counter-ion. An oxidising agent, it is used for bleaching paper and as a herbicide. It is also used in the manufacture of dyes, explosives and matches. | [Uses]
An oxidizer, like potassium chlorate, in manufacture of dyes; explosives and matches; dyeing and printing fabrics; tanning and finishing leather. Herbicide. Pharmaceutic aid (oxidizing agent). | [General Description]
Sodium chlorate in a water solution is a clear colorless liquid. SODIUM CHLORATE, AQUEOUS SOLUTION(7775-09-9) is noncombustible but SODIUM CHLORATE, AQUEOUS SOLUTION(7775-09-9) can accelerate the burning of surrounding combustible materials. This can easily occur if the material should dry out. Contact with strong sulfuric acid may cause fires or explosions. | [Reactivity Profile]
SODIUM CHLORATE decomposes upon heating forming O2; reacts with strong acids forming toxic and explosive ClO2; reacts with many substances [Handling Chemicals Safely 1980 p. 833]; metal chlorates are oxidants in the presence of strong acid; liberates explosive chlorine dioxide gas; heating a moist metal chlorate and a dibasic organic acid liberates chlorine dioxide and carbon dioxide; mixtures of perchlorates with sulfur or phosphorus are explosives [Bretherick 1979 p. 100]; mixtures of the chlorate with ammonium salts(ammonium thiosulfate), powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination of finely divided aluminum with finely divided bromates(also chlorates and iodates) of barium, calcium, magnesium, potassium, sodium or zinc can explode by heat, percussion, and friction [Mellor 2:310 1946-47]. Sodium chlorate and arsenic trioxide form a spontaneously flammable mixture [Ellern 1968 p. 51]. Mixtures of organic material and more than 10% sodium chlorate are sufficiently combustible to be hazardous at low relative humidity. Mixtures of organic material such as charcoal, sugar, flour, or shellac and sodium chlorate may be ignited by friction or shock [Chem. Safety Data Sheet SD-42 1951]. | [Air & Water Reactions]

Contact causes irritation of eyes and skin. INGESTION: May cause nausea, vomiting, diarrhea, abdominal or gastric pain, dyspnea and other symptoms. The major cause of death from a lethal dose is acute renal failure. | [Potential Exposure]
Sodium chlorate is used to manufacture dyes, explosives, in paper pulp processing and as a weed killer; used as a constituent of atratol and pramitol. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Keep victim under medical observation.
Antidotes and Special Procedures: Do not use Methylene Blue to treat methemoglobinemia from sodium chlorate as it can cause increased toxicity.

Sodium chlorate (chemical formula: NAClO3) is an inorganic compound, appearing as white crystalline powder. It has an annual yield of several hundred million tons around the world. It has many applications. Its major commercial application is for the manufacture of chlorine dioxide which is used in bleaching of pulp. Sodium chlorate can also be used for the industrial manufacture of perchlorate compounds through electrolysis. It can also be used as a non-selective herbicide to control many kinds of plants such as morning glory, Canada thistle, Johnson grass and bamboo. In addition, it can also be used as a defoliant and desiccant. It is also used for the generation of chemical oxygen which is important for emergency oxygen generation in commercial aircraft. In industry, sodium chlorate is manufactured by the electrolysis of a hot sodium chloride solution. It is also useful for making inks, cosmetics, paper and leather.
