A Comprehensive Analysis of the Core Information of Sodium Chlorate: From Basic Properties to Safe Applications
I. Basic Identification and Core Data of Sodium Chlorate
- Unique Identification Codes: PubChem CID is 516902, CAS number is 7775 – 09 – 9, EINECS number is 231 – 887 – 4, and UN numbers are 1495 (solid) and 2428 (aqueous solution). These various codes ensure its precise identification in the field of chemistry.

II. In – Depth Interpretation of the Physical and Chemical Properties of Sodium Chlorate
(I) Physical Properties
- Appearance and Morphology: Under normal conditions, it is an odorless pale yellow to white crystalline solid, and the aqueous solution is a transparent and colorless liquid. commonly found in the forms dry powder, granules, crystals.
- Solubility: It has excellent water solubility, with a solubility of 1000 g/L at 20°C, 790 g/L at 0°C, and it can increase to 2300 g/L at 100°C. It is also soluble in ethanol, ethylene glycol, liquid ammonia, etc. The presence of sodium chloride will reduce its solubility in water.
- Melting Point and Density: The melting point is 248 – 261°C (decomposition). The density is 2.49 at 59°F (about 15°C), and 2.5 g/cm³ at 25°C. It is heavier than water and will sink and dissolve rapidly when put into water.
- Other Parameters: The vapor pressure is negligible at room temperature; the refractive index is 1.515 (20°C); it has a certain deliquescence and will absorb water vapor and transform into a solution in a high humidity environment.
(II) Chemical Properties
- Oxidation Property: Although it is not flammable itself, both the solid and the 30% aqueous solution are strong oxidants. Its oxidation ability is limited in neutral or weakly alkaline environments, but its oxidation performance is significantly enhanced under acidic conditions or in the presence of induced oxidants and catalysts.
- Reactivity: It releases chlorine dioxide when reacting with acids; when in contact with wood, organic substances, ammonium salts, sulfur, etc., especially in a finely divided solid state, it is extremely likely to cause fire or explosion. When heated above 300°C, it decomposes and releases oxygen, and it completely decomposes at high temperatures.
- Stability: Under normal temperature, if there are no acidic, oxidizable substances or ammonium salts, it is relatively stable. Otherwise, when it encounters organic materials, it will pose a serious fire hazard.
- Corrosiveness: It is corrosive to zinc and low – carbon steel, and the aqueous solution is neutral.
III. Application Scenarios and Fields of Sodium Chlorate
- Agricultural Weeding Field: As a non – selective herbicide, it is widely used for weeding in non – cultivated land and wasteland. It has a rooting – out effect on plants of the Compositae and Gramineae families.
- Industrial Production Applications: It is a key raw material for the manufacture of chlorites and perchlorates. It plays an important role in the production processes of dyes, explosives, matches, inks, cosmetics, pharmaceuticals, paper, and leather. It is also used as a paper bleaching agent and an oxidant in various chemical reactions.
IV. Safety Risks and Prevention Key Points of Sodium Chlorate
(I) Hazard Identification
- Risk Categories: It belongs to oxidizing substances, harmful substances, and environmentally hazardous substances. The hazard symbols are O (oxidizing), Xn (harmful), and N (environmentally hazardous).
- Risk Phrases: Harmful if swallowed (R22); Toxic to aquatic organisms, posing a threat to the water environment (R51/53); Explosive when mixed with combustible materials (R9).
(II) Safety Protection Measures
- Operation Protection: Operators need to wear professional protective equipment to avoid dust contacting the skin, mucous membranes, and eyes. Once sodium chlorate comes into contact with the body, rinse immediately with a large amount of clean water.
- Storage and Transportation: When storing, keep it away from food, beverages, animal feed, and combustible substances. During transportation, follow the relevant specifications of UN 1495 (solid) and UN 2428 (aqueous solution) to ensure good environmental ventilation.
