Referring to liquid-liquid separationHomework Answers
a) The results will come exactly as expected because the procedure was followed correctly.
b) NaOH is a strong base, whereas NaHCO3 is a weak base. As a result of using the strong base, it will neutralize more quantity of benzoic acid than the expected. Hence, there will be a less amount of benzoic acid than that required for the reaction.
c) NaHCO3 is a weak base, whereas NaOH is a strong base. As a result of using the weak base, it will neutralize less quantity of benzoic acid than the expected. Hence, there will be a more amount of benzoic acid than that required for the reaction.

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...

Just Answer Question 5
Synthesis of 2-chloro-2-methylbutane (literature version) Concentrated aqueous hydrochloric acid (HCI, 3.3 equivalents) was slowly added to 2-methyl-2-butanol (1.0 equivalents) in a 100 mL round bottom flask with stirring. The reaction was stirred for 15 minutes at room temperature. Upon completion, the reaction mixture was transferred to a 60 mL separatory funnel and the aqueous layer was removed. The organic layer (i.e. the product) was successively washed with: (1) saturated aqueous NaCl (brine), (2) saturated aqueous NaHCO,...
