of benzoic acid, benzocaine, and biphenyl are given to students in a vial. Propose a detail separation scheme to isolate and purify each component in the mixture. Your scheme should include an acid-base extraction and purification, as well as any other necessary steps and laboratory techniques. You may use any of these given reagents (e.g., acids, bases) as needed in your separation scheme. Be specific in each reagent name and technique used in your separation scheme. The most efficient step of separation and purification chosen will receive the most credit.

A chemistry graduate student is given 300.mL of a 1.10M benzoic acid HC6H5CO2 solution. Benzoic acid is a weak acid with Ka=6.3x10^−5. What mass of KC6H5CO2 should the student dissolve in the HC6H5CO2 solution to turn it into a buffer with pH =4.40? You may assume that the volume of the solution doesn't change when the KC6H5CO2 is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits

Propose a method to separate a mixture containing phenol, benzoic acid, naphthalene, and p-nitro aniline. Phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in either sodium hydroxide or sodium bicarbonate solutions. Write out the structures of the molecules in your scheme.
