Given: 50mL of solution diethyl ether solution containing 1.00g each of benzoic acid, phenol and aniline,50 mL of sodium bicarbonate solution, 50 ml of sodium hydroxide solution, sodium sulfate and HCl. 1. Which layer in the separatory funnel (top or bottom layer) is the organic layer during an extraction process? 2. Given that sodium bicarbonate and sodium hydroxide solution are 5% by weight, what would be the volume of 1M HCl needed to be added for acidification to crystalize the...

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-

3. A crude nonacidic product mixture dissolved in diethyl ether contains acetic acid. Describe an extraction procedure that could be used to remove the acetic acid. b. When the two layers form during an ether/water extraction, what would be an easy, convenient way to tell which layer is which if the densities were not available.

Extraction of benzoic acid and 9-fluorenone using diethyl ether. (please do not include ethyl 4- aminobenzoate). I have to create a flow chart to diagram the key steps of the experiment and isolation of products. 0.100g of benzoic acid and 9-fluorenone are dissolved in diethyl ether. The extraction solvent is 5% sodium hydroxide (to extract the acidic component from the organic phase). Saturated sodium chloride is added to the organic layer. drying the organic solution: anhydrous sodium sulfate is added...

You have a separatory funnel that contains a solution of 4-methyl benzoic acid and ethoxybenzene in methylene chloride. By adding KOH (aq) into this solution for extraction, what compound(s) would be expected to form in the aqueous layer? Write the equation. Compound X has a hexane/water distribution coefficient of 2.0. (a) Does compound X have a higher or lower solubility in hexane comparing to water? (b) How much of a 3.0 g sample of compound X dissolved in 100 ml...

Product Isolation After stirring the reaction for 5 minutes and allowing the reaction mixture to cool (the reaction can be exothermic), remove the Claisen head from the conical vial. Slowly add 3 M HCl(aq) drop-wise. The solid may need to be broken up with a stirring rod or a pipet. Continue to add acid until the aqueous phase (bottom layer) tests positive with pH paper. Extractions can be done using the conical funnel...

Experiment: A mixture of equal proportions of benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene are to be separated by extraction using the solvent diethyl ether. Day 1: Part A. Isolation of the basic component: In a small beaker, dissolve 3 g of the mixture (benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene) in 30 mL of diethyl ether and transfer the mixture to a 125- mL separatory funnel (see Fig. 1) using a little diethyl ether to complete the transfer. Add 10 mL...
