1)-Briefly explain the role of the hydrochloric acid during the liquid-liquid extraction procedure. Draw the acid-base reaction between lidocaine freebase and hydronium chloride to help your discussion and circle the organic species that is more soluble in water.
2)- Briefly explain the role of the potassium hydroxide during the liquid-liquid extraction procedure. Draw the acid-base reaction between lidocaine hydrochloride and potassium hydroxide to help your discussion and circle the organic species that is would be more soluble in the organic layer. Think about the solid that you isolated. why did we chill the aqueous layer when adding KOH and why did we not want too basic of a pH>9?

Experiment 9 Acid-Base Extraction Liquid-liquid extraction utilizes the contrast solubilities of solutes in two immiscible solvents the separation of a mixture. An extracting solvent can be reactive that changes the character of solute. Consider a mixture of organic acid, organic base, and neutral substance, for example, benzoic acid, aniline, biphenyl, nd phenol. They sodium benzoate. Sodium hydroxide changes phenol to sodium phenoxide. Hydrochloric acid changes aniline to...

The Separation of Three Organic Compounds by Acid, Base Reactions and Liquid, Liquid Extraction. Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in diethyl ether. We separated the basic component by adding 3M HCl, we separated the acidic component by adding 3M NaOH. I don't understand what happens here. To isolate the acidic solution, we added 6 M NaOH and used the vacuum to recover the solid. To isolate the basic solution we added...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...
