In retrieving the compound (benzoic acid) from the aqueous phase, what is the reason for having precipitation after adding HCl in the aqueous phase? A) Carboxylate salt is less soluble in acid, so it forms precipitate after adding HCl. B) NaCl is formed after adding in HCl, and it is the precipitate. C) Carboxylate salt is neutralized after adding HCl, becomes less soluble in water and precipitates out.

Explain why benzocaine precipitates out of solution when a pH of 8 is achieved? Hint: It might be easier to approach this question from the other point of view - why is the benzocaine soluble in water before a pH of 8 is achieved? As part of the answer to this question, you must show me how benzocaine looks at an acidic pH and explain the relevance of this structure. In the box provided, draw what benzocaine looks like at...
