To make a saturated solution of benzoic acid using benzene as the solvent how much is need of each?
I can't find a number, but I found this: Benzoic acid is slightly soluble in water, soluble in ethanol, very slightly soluble in benzene and acetone. (see link on the left under Web Links) This implies not very much benzoic acid will dissolve in benzene. This other site (the MSDS for benzoic acid) says this: SOLVENT SOLUBILITY: Soluble in alcohol, ether, benzene, chloroform, acetone, carbon disulfide, oil of turpentine, carbon tetrachloride, fixed and volatile oils; slightly soluble in petroleum ether, hexane. This does make it sound fairly soluble! Hard to say which is right. This can easily be determined by experiment however!
What is the partition coefficient of benzoic acid in water and benzene if 250mg of benzoic acid is dissolved in 50ml water and 50ml benzene?
Using the formula : K= compound per ml of organic solvent/ compound per ml of water.You have 4 mg left in the aqueous layer, hence, 31 mg in the organic layer. Converting mg to g you have: (.031g / 5ml) / (.004g/ 10ml) = 15.5.
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.
Is benzene the same as benzoate?
No. Bensene and Benzoate are not the same. Benzene has the formula C6H6 (a ring of 6 carbons, each with a hydrogen bonded to it), and benzoate has the formula C6H5COO−. Benzoate is a benzene molecule that has a carboxylic acid group attached to it (except that the acid group is deprotonated). Benzoate is the conjugate base of benzoic acid. See the Web Links to the left of this answer for more information.
Prepare O-nitrotoluene from benzene and show reactions involved?
O-Nitrotoluene can be prepared from benzene via a multistep reaction process. First, benzene is nitrated to form nitrobenzene using a mixture of nitric acid and sulfuric acid. Next, nitrobenzene is methylated to form o-nitrotoluene by reacting it with methyl iodide in the presence of a base like sodium hydroxide. The final product is then separated and purified using appropriate techniques.
How do you determine the partition coefficient of benzoic acid between benzene and water?
To determine the partition coefficient of benzoic acid between benzene and water, you would first measure the concentrations of benzoic acid in each solvent layer after equilibrium is reached. Then, calculate the partition coefficient by dividing the concentration of benzoic acid in benzene by the concentration in water at equilibrium. This ratio represents how the compound distributes between the two solvents.
How can you distinguish between benzoic acid and benzene?
Benzoic acid will give brisk effervescence on reacting with sodium bicarbonate.
How does benzoic acid form dimer in toluene layer?
Benzoic acid can form dimers in a toluene layer due to hydrogen bonding between the carboxylic acid groups of adjacent molecules. The aromatic ring structure of benzoic acid allows for efficient packing in the toluene layer, promoting dimer formation. This dimerization process is driven by the favorable interactions between the molecules, such as hydrogen bonding.
What is oxidation of benzene?
Oxidation of benzene involves the addition of oxygen or removal of hydrogen from benzene molecules. This process typically leads to the formation of products with more oxygen-containing functional groups, such as phenol or benzoic acid. Oxidation of benzene can be catalyzed by various reagents or conditions, such as nitric acid or metal catalysts.
How does the structure of salicylic acid differ from that of benzoic acid?
Salicylic acid has a hydroxyl group (-OH) attached to the benzene ring, while benzoic acid has a carboxylic acid group (-COOH) attached to the benzene ring. This difference results in salicylic acid being a phenol derivative and having different chemical properties compared to benzoic acid.
Is benzoic acid or sucrose more soluble in water?
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.
Are benzene and benzoate the same?
No, benzene and benzoate are not the same. Benzene is a hydrocarbon compound with a ring structure, while benzoate is the salt or ester of benzoic acid.
To make a saturated solution of benzoic acid using benzene as the solvent how much is need of each?

What is the functional groups of benzoic acid?
The functional group of benzoic acid is a carboxylic acid group, which consists of a carbonyl group (C=O) and a hydroxyl group (OH) attached to a benzene ring. This gives benzoic acid its acidic properties.
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.
How do you detect benzene in the Grignard synthesis of benzoic acid?
Not sure what you mean... If you mean 'how is benzene used for the Grignard synthesis of Benzoic Acid,' then the answer is, bromobenzene (C6H5Br) is turned into phenyl Grignard (C6H5MgBr) by the addition of Magnesium in ether, and then dry ice (solid CO2) is added to the reaction mixture to make Benzoate (C6H5COO-), which is the conjugate base of Benzoic Acid. That has got to help you somehow.
Is benzoic acid an organic or inorganic compound?
The formula for benzoic acid is C7H6O2. As a rule, compounds that are cheifly variants of C, H, and O are organic, as is benzoic acid.
