SOLUTIONS
Which of the following statements is correct?
a) Rauolt's Law works best when applied to dilute solutions
b) Raoult's Law works best when applied to concentrated solutions
c) Raoult's Law applies exactly to all solutions
d) Raoult's Law relates the vapor pressure of the solute above the solution to the degree
of its dissocation in the solution
e) Raoult's Law applies to only non ideal solutions - ANSWER a
another possible answer is "Raoult's Law applies exactly at all concentrations only for
ideal solutions."
