How is sodium benzoate formed?
How is sodium benzoate formed?
Benzotrichloride is formed by the reaction of chlorine and toluene. In all cases, the benzoic acid is further refined to produce sodium benzoate. One way this is done is by dissolving the acid in a sodium hydroxide-solution. The resulting chemical reaction produces sodium benzoate and water.

Is Sodium Benzoate an acid or base?
Sodium benzoate is a salt of the conjugate base, the OBz- or benzoate ion. Whenever sodium benzoate dissolves in water, it dissociates into its ions. The benzoate ion then acts as a base toward water, picking up a proton to form the conjugate acid and a hydroxide ion.
What is benzoate chemistry?
benzoates are among the principal chemical preservatives. The use of benzoates in certain products in prescribed quantity (usually not exceeding 0.1 percent) is permitted in most countries, some of which require a declaration of its use on the label of the food container.
What type of chemical is sodium citrate?
citric acid
Sodium citrate is the sodium salt of citric acid. It is white, crystalline powder or white, granular crystals, slightly deliquescent in moist air, freely soluble in water, practically insoluble in alcohol. Like citric acid, it has a sour taste. From the medical point of view, it is used as alkalinizing agent.
What are the properties of sodium benzoate?
