  B) Nothing, and the HCl gas would merely bubble out of solution.
  C) The diethyl ether insoluble caffeine salt would form as a white precipitate.
  D) The acid/base reaction would release heat, which would cause the diethyl ether to start evaporating.

Question 2

If you saw the label phenylephrine HCl on a decongestant, would you worry that consuming it would expose you to the strong acid hydrochloric acid, HCl?

  B) No, because the drug is in the solid phase.
  C) No, because this is a salt made using hydrogen chloride, but it is in no way hydrogen chloride.
