To determine the partition coefficient of Benzoic Acid between Benzene and water the solubility of benzoic acid is required. The partition can then be determined by calculation.

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.


How can you distinguish between benzoic acid and benzene?

Benzoic acid will give brisk effervescence on reacting with sodium bicarbonate.


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.


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.


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!


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.


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 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.


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.


Is benzoic acid inorganic or organic?

Any molecule containing carbon that is NOT either carbon monoxide, carbon dioxide, or any allotrope of elemental carbon is considered to be organic. Seeing as benzoic acid is a carboxylic acid created by a benzene ring, it most definetely is organic


Why does benzoic acid form a dimer in benzene and not in water?

Benzene is a non polar solvent with low dielectric constant, whereas water is a polar solvent with high dielectric constant. So water can reduce the interaction between benzoic acid molecules there by preventing them from dimerizing, which cannot be done by benzene


What is the framework structure of benzoic acid?

Benzoic acid has a simple aromatic structure consisting of a benzene ring (6 carbon atoms in a hexagonal ring) with a carboxylic acid functional group (COOH) attached at position 1.
