Question
Chapter 10, Problem 6ALQ
Interpretation Introduction
Interpretation: An ice cube is added into a salt water solution what happen has to be explained.
Concept introduction: While the salt water will be a hypertonic solution for the pure water, the water will shift from an area of high attentiveness to low concentration.
Salt is frequently use in ice cream makers to make the water surrounding the within bottle cold enough to freeze the cream.

29 g of KOH is dissolved in 250. mL of water.
What is the mass percent of KOH in this solution? (use the density of water 1.00g/mL)
What is the concentration, expressed in molal (m), of this initial solution?
What is the concentration, expressed in molar (M), of this initial solution? (assume that the addition of the KOH to the water did not change the volume, which is still 250.mL)
If I add 500.mL of pure water to this 250.mL solution, what is the new concentration expressed in molar (M)?
If, instead, I took the 250. mL solution and evaporated the water until the solution had a volume of 150.mL, what would be the concentration of this this new solution expressed in molar (M)?

A friend of yours explains it to you like this: The solute and solvent can be like salt in water. The salt gets in the way of freezing in that it blocks the water molecules from joining together.
