Homework Answers
Ans. 3) you should stop shaking ang let the separating funnel hang on stand and let it stand still for some time. The two immisible liquids will form two layers and then you can separate them.

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...

Answer the following before coming to lab: 1.) Based on what you saw last week, which enantiomer of tartaric acid would you expect to co- crystallize with (SS)-1,2-diammoniumcyclohexane? 2.) If you had a neutral aqueous solution of triethylamine, would you add acid or base in order to extract it with an organic solvent? 3.) Now, consider a dichloromethane solution of triethylamine. Would you extract with acidic aqueous or basic aqueous solution in order to get the triethylamine out of the...
