Imagine you add salt to a glass of water which has been sitting on the counter…?

After adding more salt, and stirring it, you notice some salt is sitting on the bottom of the glass.

a) Is this salt-water combination a mixture, solution, suspension, or emulsion?

b) Explain why no more salt will dissolve in the water.

c) What could you do to this same glass of water to get more salt to dissolve?

d) If you put this glass of salt-water into the freezer, what would you expect to happen to it? (sorry, just saying it will freeze is not enough)
