Identify which of the following solvents in each pair would constitute the "lower" layer in a liquid/liquid extraction solution. If layer separation would not be observed, indicate this by stating "miscible".
- ethanol and diethyl ether
- chloroform and saturated brine solution (aq)
2. Would it make any difference if the methylene chloride solution containing both the basic and neutral components was washed with 1M sodium hydroxide rather than 1M hydrochloric acid? If so, what would that difference be? Would any layer separation be possible in the new solution? Would it be possible to isolate the two components from one another using 1M sodium hydroxide rather than 1M hydrochloric acid? Why or why not? Provide a balanced equation to justify your answer.
