Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in diethyl ether (4ml). We separated the basic component by adding 3M HCl, we separated the acidic component by adding 3M NaOH. I don't understand what happens here. To isolate the acidic solution, we added 6 M NaOH and used the vacuum to recover the solid. To isolate the basic solution we added 6M HCl. Here are the questions I am having trouble with... • Why...

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...

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...
