HW.4 & 5
Liquid-Liquid Extraction HW4. A student wishes to separate a mixture of the two compounds shown below. They intend to use liquid-liquid extraction to do so. NH Aniline Naphthalene A) Aniline has an amine functionality and naphthalene is purely a hydrocarbon compound. An amine functional group is acidic, basic, or neutral? asic B) Given your answer to A, fill in the missing portions of the diagram that describe the process of the separation for aniline and naphthalene. Aqueous...
The extraction of 8.0 g of a particular organic compound dissolved in 100 ml of water into diethyl ether proceeds with a distribution coefficient of 5. How much of the compound is extracted after three separate extractions using 50 ml of diethyl ether each time? ***Please show work as I am not 100% sure how to solve for X**** Thank you!
One extraction with diethyl ether is not (blank) to completely isolate the uncharged organic solute. What is the blank?
A liquid-liquid extraction is performed according to the schematic below. Which compound(s) should we expect to find in layer B? You can assume 100% of each compound is separated into its respective layer. benzoic acid diethyl ether biphenyl 5% NaOH (aq) Aqueous Organic Layer A 6 M HCl(aq) Aqueous Organic Layers C & D secondom i Vacuum Filtration Benzoic Acid
