Dissolve the mixture in an apolar organic solvent, such as diethyl ether, and extract the acid with the addition of NaOH. The bezoic acid with ionize and go into the aqueous solution. Separate the two layers and add HCl to the aqueous layer to precipitate the benzoic acid. Wash the remaing ether solution with water and dry it with an anhydrous salt. Filter the ether solution and then remove the ether, the solvent, in order to obtain the pure benzoin.

How do you separate benzoic acid from a mixture of napthalene and benzoic acid?

One way to separate benzoic acid from a mixture of naphthalene and benzoic acid is by sublimation. Naphthalene sublimes at a lower temperature compared to benzoic acid, allowing for the separation of the two compounds based on their difference in sublimation temperatures. By heating the mixture and collecting the sublimate, one can isolate benzoic acid from naphthalene.


How can you separate the mixture of chloroform aniline and benzoic acid?

One way to separate this mixture is through a process called liquid-liquid extraction. Aniline and benzoic acid are both water-soluble, while chloroform is not. By adding water to the mixture, the aniline and benzoic acid will dissolve in the water phase, leaving the chloroform to be separated out. The aniline and benzoic acid can then be recovered from the water phase by adjusting the pH of the solution.


How do you extract benzoic acid from chloroform?

To extract benzoic acid from chloroform, first dissolve the benzoic acid in water. Then, add chloroform to the mixture and shake well to allow for the benzoic acid to transfer to the chloroform phase. Finally, separate the two phases and evaporate the chloroform to obtain the benzoic acid.


How do you separate benzoic acid from a mixture of benzoic acid and toluene using extraction?

Make a solution of Sodium Hydroxide or Sodium Carbonate and do three to four solvent solvent extractions using the aqueous base and the mixture o benzoic acid and toluene. Because benzoic acid reacts with base to form the water soluble carboxylate ion, it will react and the dissolve in the aqueous solution. Upon separation of the two phases acidify the aqueous extract with dilute HCl, a white needle-like precipitate of benzoic acid will form when the solution becomes acidic. Simply filter the crystals, wash with cold water, and then recrystallize using a mixture of 50/50 water and methanol or some other suitable solvent.


What is the significance of the benzoic acid rf value in chromatography analysis?

The benzoic acid rf value in chromatography analysis is significant because it helps to identify and separate different compounds in a mixture based on their relative migration distances. By comparing the rf value of benzoic acid to other compounds, scientists can determine the purity and composition of a sample.

How pure benzoic acid may be separated form a solution of sand and benzoic acid?

To separate benzoic acid from a solution of sand and benzoic acid, you can use solvent extraction. Benzoic acid is soluble in organic solvents like diethyl ether, while sand is not. By adding diethyl ether to the solution, the benzoic acid will dissolve in the ether, allowing you to separate it from the sand by decanting or filtration. Then, evaporate the diethyl ether to recover the pure benzoic acid.

How a mixture of sand and benzoic acid which is soluble in hot water might be separated to provide benzoic acid?

Sand is insoluble in water and can be easily filtered.


In the laboratory a student named Georgia weighed 5.35 grams of an unknown solid mixture containing benzoic acid copper II sulfate and sand she added 15 ml of acetone to her sample which dissolved?

The benzoic acid in the mixture dissolved in the acetone because it is soluble in acetone. Copper (II) sulfate does not dissolve in acetone like benzoic acid does. The sand in the mixture does not dissolve in acetone as it is insoluble.


What is the eutectic temperature for benzoic and mandelic acid?

The eutectic temperature for the benzoic and mandelic acid system is approximately 119°C. At this temperature, both compounds will fully dissolve in each other to form a eutectic mixture, exhibiting the lowest melting point in the system.


Is benzoic acid react with sodium bicarbonate?

Yes, benzoic acid will react with sodium bicarbonate to produce sodium benzoate, carbon dioxide, and water. This reaction can be used to extract benzoic acid from a mixture as it is relatively insoluble in water but soluble in sodium bicarbonate solution.
