Suppose that a student extracted the ether soution first with koh (excess). in other words, the student skipped the step with the k2hpo4. a. draw the structures of the species that would be present (in significant quantities) in the ether layer. b. draw the structures of the species that would be present (in significant quantities) in the aquous layer. c. would adding k2hpo4 to the organic layer be of any use in an attempt to fix this error and separate and isolate the three compounds? explain d. would adding k2hpo4 to the aqueous layer be of any use? explain.
why is it not suprising to find some caffeine in the isolated aspirin and/or acetaminophen?
gravity filtration or decanting may be used to separate the solid from the liquid after using na2so4 on the final ether layer. a. which method did you use? b. for that method where was the sodium sulfate after the separation? c. where was the caffeine? d. where did the water go?
