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.
Solubility of benzoic acid in acetone is 1.350 M
The density of Benzoic Acid is approximately 1.27 g/mL at room temperature.
The pKa of mandelic acid is around 3.4 for the carboxylic acid group and around 9.8 for the phenolic hydroxyl group. This means that mandelic acid is a weak acid, with the carboxylic acid group being more acidic than the phenolic hydroxyl group.
it is soluble in chloroform. Chloroform is nonpolar.
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.

Yes it is. Mandelic Acid is soluble up to 15g per 100ml of water (essentially a 15% concentration)
Yes, benzoic acid can react with hypochlorous acid in water at room temperature to form chlorobenzoic acid. This reaction is typically slow and requires higher temperatures or catalysts for efficient conversion.
Benzoic acid is a carboxylic acid that is typically solid at room temperature and has a characteristic acidic smell. Methyl benzoate is an ester that is usually a liquid at room temperature and has a sweet, fruity odor. A chemical test like adding a base to benzoic acid to form a salt or reacting methyl benzoate with an alcohol to get back the carboxylic acid can help distinguish between the two.
Benzoic acid is soluble in kerosene.
Sucrose is more soluble in water than benzoic acid. Sucrose is a polar molecule that can form hydrogen bonds with water molecules, increasing its solubility. Benzoic acid, while also polar, has a benzene ring which reduces its ability to form hydrogen bonds with water, making it less soluble.
Cooling the hot solution containing dissolved benzoic acid in an ice bath will cause the benzoic acid to crystallize out of solution due to the decrease in temperature. This rapid cooling process helps to promote the formation of pure benzoic acid crystals and allows for easier separation from the solution.
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.
