Diethyl Ether Benzoic Acid Water

Benzoic acid is soluble in diethyl ether but not water however benzoic acid is extracted from diethyl ether with aqueoussodium hydroxide.

Diethyl ether benzoic acid water. Diethyl ether or simply ether is an organic compound in the ether class with the formula c 2 h 5 2 o sometimes abbreviated as et 2 o see pseudoelement symbols it is a colorless highly volatile sweet smelling ethereal odour flammable liquid it is commonly used as a solvent in laboratories and as a starting fluid for some engines. B in the reaction of part a label the acid the base conjugate acid and conjugate base. After extraction the ether layer is removed dried concentrated and you recovered 0 79 mg of benzoic acid. Benzoic acid is more soluble in diethyl ether than water.

It was formerly used as a general anesthetic until. It is commercially manufactured by the chemical reaction of toluene a hydrocarbon obtained from petroleum with oxygen at temperatures around 200 c about 400 f in the presence of cobalt and manganese salts as catalysts. You weight out exactly 1 00 mg of benzoic acid and dissolve it in a mixture of 2 0 ml of diethyl ether and 2 0 ml of water. Benzoic acid is more soluble in diethyl ether than water.

Below is my work. Benzoic acid or benzene carbonic acid is a monobasic aromatic acid moderately strong white crystalline powder very soluble in alcohol ether and benzene but poorly soluble in water 0 3 g of benzoic acid in 100 g of water at 20 c. Bear in mind that ether is less dense than water so the extract would be on top. What is the distribution coefficient k value ether water for this system.
