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.
Which is more acidic formic acid or benzoic acid?
Benzoic Acid
Why o-hydroxy benzoic acid is strong than m-hydroxy benzoic acid?
nswers for Orthohydroxybenzoic Acid Is More Acidic Then The Parahydroxy Benzoic Acid
How do you separate benzoic acid from a mixture of CONGO RED and salt?
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.
What is the eutectic temperature for benzoic and mandelic acid?
The eutectic temperature for benzoic acid and mendelic acid mixture is 105-106º C. This is usually about 60% mandelic acid and 40% benzoic acid.
How much water should be used for the recrystallisation of benzoic acid?
depends on how much benzoic acid you use. if you have 0.5g of benzoic acid , you need 30ml of water as a solvent.

Why can not benzoic acid be dissolved in water at room temperature?
To be soluble a solution must be capable of being dissolved in a solvent, usually water. The HCL cannot ionize into H+ with the COOH ring in the Benzoic acid. Benzoic is hydrophobic in this solution.

Is Benzoic acid intensive or extensive?
Neither. Benzoic acid is... benzoic acid. Intensive and extensive are properties are characteristics of elements and compounds such as color, density, odor, conductivity, etc. To say benzoic acid is extensive or benzoic acid is intensive doesn't make sense.
What is the eutectic temperature for benzoic and mandelic acid?
The eutectic temperature for benzoic acid and mendelic acid mixture is 105-106º C. This is usually about 60% mandelic acid and 40% benzoic acid.
Chemical name of salicyclic acid?
O-hydroxy benzoic acid or 2-hydroxy benzoic acid.
Is benzoic acid a strong or weak acid?
Yes. Benzoic acid is an organic compond with the formula C7H5CO2H
What is the solubility of Benzoic acid in acetone?
Solubility of benzoic acid in acetone is 1.350 M
