Acid/Base Extraction
1. Provide a flow chart detailing the acid/base
extraction/separation of the compounds shown below. Your answer
must employ the following reagents: methylene chloride,
hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M),
10% sodium bicarbonate (aq). Clearly indicate the product(s) and
layers formed following each step of your separation scheme.
IMPORTANT: p-cresol is soluble in sodium hydroxide solution but
insoluble in neutral water or sodium bicarbonate solution. 2-

In the acid/base extraction lab, a carboxylic acid was separated
from fluorene by extracting the carboxylic acid into the aqueous
layer using NaOH solution (a review of this experiment before lab
will be helpful). Phenols (aromatic alcohols) can also be separated
using this method. In a mixture of a phenol and a non-reacting
organic compound, the phenol may be selectively removed from an
organic solvent by extracting with a dilute NaOH solution. After
separating the organic and aqueous layers, the...

To do any extraction, you’ll need two liquids or solutions. They must be insoluble in each other. a. What does it mean to have 2 insoluble liquids or solutions? b. I have listed twelve liquids and solutions below. Identify if each solution is considered aqueous or organic. Water, acetone, 1.0 M NaOH, 1.0 M HCl, diethylether, brine (saturated sodium chloride in water), dichloromethane, 10% sodium bicarbonate solution, ethyl acetate, chloroform, ethanol, hexane. 2. Which of the organic liquid(s) from 1b...

Why is the partition coefficient different for benzoic acid and sodium benzoate? Explain chemical reasons why the two values differ. Especially note the type of intermolecular forces that exist in the solute and the two solvents. Partition Coefficient of Benzoic Acid Benzoic acid in water layer and organic layer (dichloromethane) as organic layer. 3.1 Partition Coefficient of Sodium benzoate Benzoic acid in aqueous layer (water and sodium bicarbonate) and dichloromethane as organic layer. 0.12
