1. If you repeated steps 1-6 (in your green book) using 20 mL of the solution rather
than 6 ml, how would the results be different?
How would the results be the same? Explain your responses.
2. Give a specific example for each of the following types of solutions.
a. gas dissolved in gas:
b. gas dissolved in liquid:
c. solid dissolved in solid:
d. solid dissolved in gas:
3. Use the information in the solubility table below to respond to each of the
following questions.
a. Which salt is most soluble in water at 0 °C?
b. Which salt is least soluble in water at 0 °C?
c. Which salt is least soluble in water at 100 °C?
d. What is the mass % of NaCI in a saturated solution at 40 °C? (Show all
