What should be the approximate pH and composition of aqueous system to dissolve benzoic acid?
To dissolve benzoic acid, the aqueous system should be slightly acidic with a pH around 2-3. This can be achieved by adding a small amount of hydrochloric acid to water. Benzoic acid is sparingly soluble in pure water but dissolves more readily in an acidic solution due to the formation of benzoate ions.
What else can I help you with?
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.
Can benzoic acid dissolve in acetone?
Yes, benzoic acid can dissolve in acetone because both are polar compounds. Acetone is a polar aprotic solvent that can effectively dissolve polar molecules like 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.
How does benzoic acid dissociation affect its solubility and bioavailability in aqueous solutions?
When benzoic acid dissociates in water, it forms benzoate ions which are more soluble than the undissociated acid. This increased solubility enhances the bioavailability of benzoic acid in aqueous solutions, making it easier for the body to absorb and utilize.
What is the solubility of Benzoic acid in acetone?
Solubility of benzoic acid in acetone is 1.350 M

What happen when dissolve salt with benzoic acid?
Any reaction occur.
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.
What is the chemical name of benzoic acid after heating?
The products of the thermal degradation of benzoic acid are carbon dioxide and water.
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.
Does benzoic acid dissolve in ligroin?
yes it does with heat, although it might take a super long time when heat up.
What happens when benzoic acid dibromobenzene and ether are combined?
Yes all organic compounds dissolve in ethers.
What results from a mixture of benzoic acid to and HCL?
You will get benzoic acid as a result. The benzoic salt will gain a Hydrogen from the HCl; thus, becoming benzoic acid, and the Cl shall remain by itself in suspension if you're mixing the two together in an aqueous solution.
