5 days ago · Sodium benzoate is a common food preservative, widely used to prevent the growth of microbes in acidic foods such as salads, sodas, fruit juices, pickles, and condiments. Chemically known as C7H5NaO2, it is the sodium salt of benzoic acid and is recognized by its E number, E211.
2 days ago · Sodium benzoate is a weakly basic drug that does not react with the acid in an aqueous medium strongly and gives an unsatisfactory endpoint. In a nonaqueous medium, the endpoint is satisfactory. therefore glacial acetic acid is used as a solvent for the reaction between sodium benzoate and perchloric acid.
