Question

During an extraction, if you become uncertain about which laser is the organic layer, how could you determine it experimentally? From the results of this experiment, what can you conclude about the solubilities of each component in your mixture? Write specific chemical equations for each reaction that took place, using the skeletal structures of the molecules Should it make any difference if the mixture is extracted first with HCI or NaOH? Explain. Give a flow chart for separating a mixture containing phenol, benzoic acid, naphthalene, and p-nitroaniline 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 flow chart. Calculate the mass of A extracted in Section A above when four 25 mL portions of the solvent was used in the extraction.
