Separating ethyl-4-aminobenzoate, phenanthrene, and salicylic acid in a solution. Don't know the concentrations of any of them.
Planning to use HCl to precipitate the salicylic acid out, but will have access to 6 M and 1 M and I'm not sure which to use.
Then adding NaOH to organic layer to precipitate out the ethyl-4-aminobenzoate, but again I'm not sure what molarity to use between the 1 M and 6 M (we will have access to 1 M and 6 M NaOH too).
Finally, planning to add NaCl to precipitate out the phenanthrene.

    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...

    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 will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

    Construct a flow chart describing the seperation of the mixture and the isolation of each compound in this experiment. (Lab steps/procedures includes for reference) 4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...
