using the procedures, we used dichloromethane as the unknown
mixture and i was able to extract benzoic acid for an acid,
5-chloro-2-methoxyanaline for a base compound and biphenyl for
neutral compound.
i don't know if that answers the missing part but if it didn't
could you be specific please? thank you!

Provide a flow chart detailing the acid/base extraction/separation of the compounds show below. Your answer must employ the following reagents: methylene chloride, hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M), 10% sodium bicarbonate (aq). Clearly indicate the product(s) and layers formed following each step of your separation scheme. IMPORTANT: p-cresol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. 2-ethylbenzoic acid is soluble in both sodium hydroxide and sodium bicarbonate solutions. Use...
