A mixture of compounds containing dimethylamine, phenol, ammonia, and acetic acid is separated using liquid-liquid extraction as follows: Step 1: Concentrated HCl is added followed by draining the aqueous layer. Step 2: Dilute NaOH is added to the organic layer followed by draining the aqueous layer. Step 3: Concentrated NaOH is added to the organic layer followed by draining the aqueous layer. Which compound would you expect to be extracted into the aqueous layer after the addition of dilute NaOH,...

Acid/Base Extraction
ACID/BASE EXTRACTION 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. HINT: phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in both sodium hydroxide and...

An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...

please provide an equation for the reaction of the aqueous layer with Hdl. The following experiment was done: add 1g of 1:1 mixture of benzoic acid and naphthalene. add 30 ml of dichloromethane to dissolve. Add solution to a separatory funnel. Add 15ml of NaOH, shake and separate the two layers. with the aqueous layer, containing NaOH, combine 6M HCl until you have reached a pH of 2. ice to speed up the production of crystals.
