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.
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.
Can benzoic acid dissolve in acetone?
It is partially soluble.
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.
In chimistry laboratory how can you separate benzoic acid from para- nitro-anilin with extraction prgress?
Separating benzoic acid from para-nitroaniline requires a mixing stage before the separation stage. The process also requires aqueous sodium hydroxide.

What happen when dissolve salt with benzoic acid?
Any reaction occur.
What happens when benzoic acid dibromobenzene and ether are combined?
Yes all organic compounds dissolve in ethers.

Does benzoic acid dissolve in ligroin?
yes it does with heat, although it might take a super long time when heat up.
What 2 substances will be formed when hydrochloric acid reacts with sodium hydroxide?
HCl + NaOH = H2O + NaCl Or, water and table salt--which will dissolve in water. Benzoic acid, C6H5COOH, will not be formed; neither of the two starting chemicals contains carbon, and benzoic acid contains a lot of it. - - - - - Benzoic acid and sodium chloride
Why is benzoic acid is extracted into ether then extracted into an alkali solution prior to being precipitated with strong acid in its preparation with grignard reagent?
When you're attempting to extract benzoic acid from other organic compounds, it is necessary to change its pH by adding a layer of an basic compound such as 1M NaOH so that the benzoic acid then can be separated from the organic layer within a separatory funnel. When in NaOH, the benzoic acid loses a proton and thus becomes its conjugate base (the benzoate ion). The benzoate ion is charged and thus become miscible in the aqueous layer. To extract benzoic acid (ie get it to precipitate out of solution), a strong acid such as HCl must be added to solution. After the extraction, lower the pH of the solution, and recrystalize (use ice after the recrystalization to get benzoic acid crystals to crash out).
Is benzoic acid soluble in kerosene.?
Benzoic acid is soluble in kerosene.
What is the derivative of benzoic acid?
Salts of the benzoic acids are called benzoates.
