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.
Why is the solubility of benzoic acid poor in cold water?
Benzoic acid has poor solubility in cold water because it is a non-polar molecule, while water is a polar solvent. Polar solvents like water tend to interact more strongly with other polar molecules rather than non-polar molecules, making it difficult for benzoic acid to dissolve in cold water.
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.
Chemical name of salicyclic acid?
O-hydroxy benzoic acid or 2-hydroxy benzoic acid.
What is equation for rxn of benzoic acid with K2CO3?
The reaction equation for benzoic acid reacting with K2CO3 is: C6H5COOH + K2CO3 -> C6H5COOK + CO2 + H2O

How prepare sodium benzoate?
To prepare sodium benzoate, you can neutralize benzoic acid with sodium hydroxide. This reaction forms sodium benzoate and water. The resulting sodium benzoate can then be purified through crystallization for use as a preservative in food and beverages.
How do you separate benzoic acid from a mixture of CONGO RED and salt?
To separate benzoic acid from a mixture of CONGO RED and salt, first dissolve the mixture in water. Benzoic acid is soluble in hot water, while CONGO RED and salt are not. Then, cool the solution to separate out the benzoic acid crystals by filtration. Finally, dry the crystals to obtain pure benzoic acid.

Is benzoic acid soluble in kerosene.?
Benzoic acid is soluble in kerosene.
What is the solubility of Benzoic acid in acetone?
Benzoic acid is soluble in acetone. At room temperature, about 6.7 g of benzoic acid can dissolve in 100 mL of acetone.
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.
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 derivative of benzoic acid?
The derivative of benzoic acid is sodium benzoate, which is often used as a preservative in food and beverages due to its antimicrobial properties. Sodium benzoate is the sodium salt of benzoic acid and is more soluble in water than benzoic acid itself.
What is the classical name for the C6H6COOH?
The classical name for C6H5COOH is benzoic acid.
What is the trade name for benzoic acid?
The trade name for benzoic acid is E210.
Why is vacuum filtration faster than gravity filtration?
Vacuum filtration is used instead of gravity filtration in order to achieve a dryer product in less time. The faster process of vacuum filtration allows the slurry to remain cold and in cases such as with benzoic acid more crytals will remain formed at colder temperatures. Gravity filtration is most useful when the solid is to be discarded and the filtrate (the liquid that flows through the filter paper) kept. Vacuum filtration is often faster than gravity filtration and is most useful if the solid must be kept or if a filtration must be done rapidly. A vacuum from an aspirator or a vacuum pump is used to pull the liquid through a funnel containing a piece of filter paper, while the solid is left on the paper.
