4. Identify a solution other than 3M NaOH which could be used to extract the acid component of the mixture into the aqueous layer. (Solvents: Acetone, Ethanol, Methanol, 3M HCI, NaCl (aq). Na2CO3(aq), NaHCO3(aq). Explain your choice and write an acid/base equation similar to Reaction 2 with your acid unknown and the solution of choice as reactants. 3pts 5. Considering uncharged drugs absorb better, do you expect lidocaine (an anesthetic) to be more easily absorbed in the stomach (pH2) or intestine (pH7.5)? Explain 2pts
