Sodium citrate, also known as "sodium citrate", has the chemical formula C6H5Na3O7 and a chemical weight of 258.07. It is a compound with a colorless rhombic columnar crystal that is stable in air and has a relative density of 1.859. Soluble in water and glycerol, slightly soluble in ethanol. The aqueous solution is slightly alkaline and has a refreshing taste. When heated to 100 ℃, it becomes a dihydrate salt. The latter is a colorless monoclinic columnar crystal or granular powder, which is easily soluble in water. At 150 ℃, it becomes anhydrous and decomposes at higher temperatures. Commonly used as a buffering agent, chelating agent, and bacterial culture medium, it is used in medicine for diuresis, phlegm elimination, sweating
