Chapter 12, Problem 12.115QP

Two samples of sodium chloride solutions are brought to a boil on a stove. One of the solutions boils at 100.10°C and the other at 100.15°C.

1. a Which of the solutions is more concentrated?
2. b Which of the solutions would have a lower freezing point?
3. c If you split the solution that boils at 100.1°C into two portions, how would the boiling points of the samples compare?

Which of the following statements do you agree with regarding the determination of your answer for part c?

1. I. The question cannot be answered with certainty without knowing the volumes of each portion.
2. II. Making the necessary assumption that the two samples have equal volumes, I was able to correctly answer the question.
3. III. The volumes that the sample was split into are irrelevant when determining the correct answer.
