Sodium nitrate CAS: 7631-99-4;15621-57-5 EINECS 231-554-3 Molecular Formula: NNaO3 Sodium nitrate - Properties Sodium nitrate appears as colorless and transparent rhombic crystals, or white or slightly yellow particles or powder at room temperature. It tastes salty and slightly bitter. Easily deliquescent in humid air. The relative density is , the melting point is 308°C, the boiling point is 308°C, and it decomposes when boiling to generate NaN02 and 02. It is extremely soluble in water, liquid ammonia and glycerin, difficult to dissolve in ethanol and methanol, and extremely difficult to dissolve in acetone. When dissolved in water, the water temperature drops and the aqueous solution becomes neutral. Sodium nitrate is an oxidizing agent that can cause combustion and explosion when in contact with organic matter such as sawdust, cloth, and oil. Sodium nitrate is used to make potassium nitrate, mining explosives, picric acid, dyes and other materials. Nitration reagent f
