Consider two hypothetical pure substances, AB(s) and XY(s). When equal molar amounts of these substances are placed in separate 500-mL samples of water, they undergo the following reactions:
AB(s) → A+ (aq) + B" (aq)
XY(s)--XY(aq)
a. Which solution would you expect to have the lower boiling point? Why? xy has the lower ooling roinr. a. urgm xy non-evectroyhc AB- electrolytic
b. Would you expect the vapor pressures of the two solutions to be equal? If not, which one would you expect to have the higher vapor pressure? Soute cany be caprated beteust in s in ions fsm so vaer csure xy s graer than Ae
c. Describe a procedure that would make the two solutions have the same boiling point.
d. If you took 250 mL of the AB(aą) solution prepared above, would it have the same boiling point as the original solution? Be sure to explain your answer. d.
